摘要：
A transfer printing sheet comprising a base sheet, a releasing resin layer coating the surface of the base sheet entirely or partially, a layer of a pattern printed on the release resin layer and comprising an elastic high-polymer resin and a pigment in admixture, and a layer containing an agent for dissolving synthetic fibers and covering the entire surface of the pattern layer. When the sheet is subjected to heat and pressure, the pattern of the pattern layer can be transferred onto a fabric of synthetic fiber in contact with the layer containing the dissolving agent to give a distinct print having a soft hand and outstanding color fastness against rubbing, washing and light.
技术问题语段：
However, the former method wherein printing ink dyes are used requires a cumbersome process including a long period of heat treatment with steam, followed by washing with water for the removal of glue, drying, etc. for synthetic fibers of any given type; fails to produce a distinct design although the colored article retains a good hand or feel; and is totally unusable for colored fabrics since a white dye is not available which has hiding power as is necessary in such a case.|Synthetic resins useful for the above mentioned method are chiefly polyacrylate copolymer resins, melamineformaldehyde resins, etc., which assure very satisfactory color fastness and exhibit resistant properties on cotton, hemp, rayon and like natural fibers, but which nevertheless are very low in strength on shaped articles of synthetic fibers which are chiefly polyester fibers and further include nylon, polyacrylyic and like fibers.|Moreover, when crosslinked as described above, these resins seriously impair the hand or feel of synthetic fibers and do not always exhibit improved durability.|For example, the dry sublimation transfer printing method for polyester fibers is not usable for colored articles.|With this method, however, the resin coating is merely adhered to the article printed therewith by plastic flow contact with the otherwise unmodified fibers of the article, such that the print is low in durability, especially in resistance to rubbing and washing, like those prepared by direct printing.|Thus, extreme difficulties have heretofore been encountered in attempts at printing sharp colorfast designs or patterns on shaped articles of various synthetic fibers.|When particles of the dissolving agent are used, such as by spraying or electrostatic implanting, the dissolving agent can be applied while the surface of the pattern layer 3 which has previously been printed is still wet or tacky, but the surface of the resulting transfer sheet is then likely to have difficulty in intimately adhering to the article 5 to be printed.|Although dependent on the properties of the synthetic fibers at the surface of the article 5 to be printed, the use of an excess of the dissolving agent is generally objectionable, since the dissolving agent will then either completely break down the fiber structure or otherwise hamper the adhesion of the pattern layer 3 thereto.
技术功效语段：
When the above three-layer or multi-layer transfer printing sheet is subjected to printing pressure and heat with the surface of the dissolving agent layer in contact with the article of synthetic fiber to be printed therewith, the dissolving agent of the dissolving agent layer advantageously suitably dissolves or otherwise modifies the adjacent synthetic fibers of the article and, at the same time, the pattern layer is transferred, e.g. under heat flow, to the article and fixed thereto at the so modified fibers thereof. Hence, it has been found that the article can be printed by way of the present invention with a colorfast and distinct pattern in a flexible pattern layer without impairing the hand or feel of the article, irrespectively of whether the article is colorfast or not.
权利要求：
What is claimed is:
1. Transfer printing sheet for transferring a pattern onto an article of synthetic fibers, comprising a base sheet having a coatable surface, a releasing resin layer at least partially coating the coatable surface of the base sheet, a pattern in the form of a pattern layer printed on the releasing resin layer and comprising an elastic high polymer resin and a pigment in admixture, and a dissolving agent layer containing an agent of monomeric organic compound constitution or of inorganic compound constitution for dissolving adjacent surface portions of synthetic fibers of an article onto which the pattern is to be transferred, the dissolving agent layer covering the entire surface of the pattern layer, whereby the pattern of the pattern layer can be transferred onto the article of synthetic fiber when the sheet is subjected to heat and printing pressure with the dissolving agent layer in contact with the article.
2. Sheet of claim 1 wherein the elastic high polymer resin of the pattern layer comprises a heat-crosslinkable resin.
3. Sheet of claim 1 wherein the pattern layer comprises a composite layer formed of a plurality of superposed sub-layers.
4. Sheet of claim 1 wherein the pattern layer comprises a composite layer formed of a colored pigment sub-layer and a white pigment sub-layer superimposed thereon.
5. Sheet of claim 1 wherein the dissolving agent layer is formed by printing the pattern layer with a printing ink containing the agent for dissolving synthetic fibers.
6. Sheet of claim 1 wherein the elastic high polymer resin has a melting or softening point of substantially between about 50.degree.-150.degree. C.
7. Method of printing a substantially colorfast and distinct pattern onto the surface of an article of synthetic fiber which comprises applying heat and mechanical pressure to the transfer printing sheet of claim 1 while the dissolving agent layer thereof is in operative contact with the adjacent synthetic fibers at the surface of the article and sufficiently for the corresponding dissolving agent to modify such synthetic fibers to render the surface portions thereof locally receptive to the elastic high polymer resin of the pattern layer and for such elastic high polymer resin to flow into and adhere firmly to the dissolving agent modified synthetic fibers at the surface of the article and thereby transfer the pattern of the pattern layer to the article.
8. Method of claim 7 wherein the printing is effected at a temperature of substantially between about 100.degree.-220.degree. C. for a duration of substantially between about 2-10 seconds.
9. Method of claim 8 wherein the elastic high polymer resin has a melting or softening point of substantially between about 50.degree.-150.degree. C.
10. Article printed by the method of claim 7.
11. Article printed by the method of claim 8.
12. Article printed by the method of claim 9.
