[0024] Example 1:
[0025] The preparation of the photocurable composite paint printing color paste composition and the processing method for fabric printing are as follows:
[0026] (1) Preparation of acrylate copolymer: Mix 30 parts of methyl acrylate, 30 parts of n-butyl acrylate and 40 parts of glycidyl acrylate in the reactor, then add 150 mL of solvent butanone, and when the solution is heated to 80 At ℃, a mixture consisting of 7 parts of initiator azobisisocyanate and 10 parts of butanone was added dropwise with stirring. After the dropwise addition, the reaction was performed at a constant temperature for 3.5 hours, and then the unreacted material and butanone were removed under reduced pressure. , to obtain acrylate copolymer;
[0027] (2) Preparation of photocurable composite paint printing paste: add 100 parts of acrylate copolymer into the container, then add 2 parts of terminal epoxy siloxane, 2 parts of epoxy siloxane hybrid, 3 parts of photoinitiator onium sa...

[0031] Example 2:
[0032] The preparation of the photocurable composite paint printing color paste composition and the processing method for fabric printing are as follows:
[0033] (1) Preparation of acrylate copolymer: 25 parts of methyl acrylate, 25 parts of n-butyl acrylate and 50 parts of glycidyl acrylate were mixed into the reactor, and then 150 mL of solvent butanone was added. When the solution was heated to 80 °C , 7 parts of initiator azobisisocyanate and 10 parts of butanone were added dropwise under stirring, after the dropwise addition, the reaction was performed at a constant temperature for 3.5 hours, and then the unreacted material and butanone were removed under reduced pressure to obtain acrylate copolymer;
[0034] (2) Preparation of photocurable composite paint printing paste: first add 100 parts of acrylate copolymer obtained in step (1) into the container, then add 2 parts of epoxy-terminated siloxane and 4 parts of epoxy resin in turn Siloxane hybrid...
