Title:
STICKING INHIBITOR AND HEAT-SENSITIVE TRANSFER RECORDING FILM
Document Type and Number:
Japanese Patent JP3452752
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable a heat-sensitive transfer recording film to have high lubricity and also to be free from the splash of a heat-sensitive ink or the generation of an interference with a transfer action by forming a sticking inhibiting layer composed of a polydimethyl siloxane block copolymer.
SOLUTION: A polydimethyl siloxane block copolymer to be used for the sticking inhibiting layer of the heat-sensitive transfer recording film is composed of three parts such as (a1*a2)1, a1* (a1*a2)m a2*(a2*a2)n. l, m, n are an integer of 1-10: a1 is the polydimethyl siloxane part of the structure shown by formula (n is an integer of 1-50); and a2 is a vinyl polymer part. When forming the sticking inhibiting layer, a solution of the polydimethyl siloxane block copolymer solved in an organic solvent is applied to the surface of a base film and then is dried. According to an experiment, a sheet on which the sticking inhibiting layer is formed demonstrates the favorable effect of the inhibitor which eliminates the splash of an ink, a sticking phenomenon and print irregularities.
