Abstract
Abstract 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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
148 words
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.
Claim 2
Dependent Claim
148 words
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.
Claim 3
Dependent Claim
18 words
Sheet of claim 1 wherein the elastic high polymer resin of the pattern layer comprises a heat-crosslinkable resin.
Claim 4
Dependent Claim
19 words
Sheet of claim 1 wherein the pattern layer comprises a composite layer formed of a plurality of superposed sub-layers.
Claim 5
Dependent Claim
25 words
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.
Claim 6
Dependent Claim
27 words
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.
Claim 7
Dependent Claim
22 words
Sheet of claim 1 wherein the elastic high polymer resin has a melting or softening point of substantially between about 50°-150° C.
Claim 8
Dependent Claim
122 words
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.
Claim 9
Dependent Claim
27 words
Method of claim 7 wherein the printing is effected at a temperature of substantially between about 100°-220° C. for a duration of substantially between about 2-10 seconds.
Claim 10
Dependent Claim
22 words
Method of claim 8 wherein the elastic high polymer resin has a melting or softening point of substantially between about 50°-150° C.
Claim 11
Dependent Claim
8 words
Article printed by the method of claim 7.
Claim 12
Dependent Claim
8 words
Article printed by the method of claim 8.
Claim 13
Dependent Claim
8 words
Article printed by the method of claim 9.
