Photocurable compositions for use as ceramic ink vehicles

摘要

A radiation-curable ceramic ink composition comprising: (a) from 2 to 30 percent by weight of at least one acrylated polycaprolactone diol polyurethane having a molecular weight in the range from 600 to 3500; (b) from 2 to 40 percent by weight of a reactive diluent system comprising at least one addition-polymerizable acrylic monomer which is copolymerizable with said acrylated polycaprolactone diol polyurethane; (c) from 60 to 90 percent by weight of at least one ceramic frit.
