Abstract: PURPOSE: A method of forming a gelatin subbing layer in a film for printing is to provide the subbing layer with more powerful adhesive strength and good physical properties. CONSTITUTION: An epoxy silane of specific structure having an epoxy group is first reacted with an amino group or a carboxyl group of gelatin alone or a mixed resin of gelatin and acrylic emulsion to graft the silane on the gelatin. Thereafter, the grafted silane is hydrolyzed using a sol-gel method in the presence of suitable acid or base, forming a dimmer or an oligomer by a self-condensation reaction, which is cured to form a subbing layer onto a film having a primer layer. At this time, 2 to 7 percent by weight of the epoxy silane is used relative to the amount of the gelatin and 20 to 100 percent by weight of the acrylic emulsion relative to the gelatin is used.
