PURPOSE:To obtain the title composition having excellent wetting characteristics and excellent adhesiveness to a molded article containing silicone resin or fluororesin, by mixing a marking ink with a specified mixture or reaction product and a cure accelerator. CONSTITUTION:A mixture or reaction product (B) is obtained by mixing or reacting a reactive linear silicone polymer (a) of formula I [wherein R<1> is H, a 1-5C (substituted)monovalent hydrocarbon group, OH, a hydrolyzable group except halogen, or a hydrocarbon group containing amino or epoxy; R<2> is H, a (substituted)monovalent hydrocarbon group; n is 3 or greater] with a reactive branched silicone polymer (b) consisting of a unit of formula II (wherein R<3> is a hydrocarbon group having amino or epoxy; a and b are each 0-3 and a+b=3) and an SiO2 unit in a weight ratio of (a) to (b) of 0.5-2:1. A marking ink (A) preferably consisting mainly of a thermosetting phenolic, epoxy or alkyd resin is mixed with 0.05-10pts.wt., based on 100pts.wt. component A, component B and 0.05-10pts.wt., based on 100pts.wt. component B, curing catalyst (C). |
