METHOD FOR PRODUCING FLEXOGRAPHIC PRINTING PLATE AND FLEXOGRAPHIC PRINTING PLATE

摘要

Provided is a method of manufacturing a flexographic printing plate with which it is possible to prevent plate surface contanimation even in the printing for long time. A method for manufacturing a flexographic printing plate, characterized in that, a liquid containing an amino-modified silicone compound is made to contact with a flexographic printing plate containing a latex having gelation degree of not less than 50% by mass. Said latex occupies preferably not less than 30% by mass of the printing resin plate, and amino group equivalent of the amino-modified silicone compound is preferably not less than 500 g/mol.
