Abstract
PURPOSE: To provide the titled capsule which enables extremely simple estimation and determination of the heat resistance, water resistance and solvent resistance of the adhesive capsule and the degree of breakage of the capsule under pressure, by using a composition containing an oil-soluble dye as well as an adhesive as the core substance of an adhesive-containing microcapsule.
CONSTITUTION: The core substance of a microcapsule containing an adhesive (e.g. and elastomer adhesive composed mainly of isoprene rubber, etc.) is compounded with an oil-soluble dye[preferably an electron-donative colorless dye such as 3,3-bis(p-dimethylaminophenyl)-6-dimethylaminophthalide, etc. at a concentration of 1W5.0% in the adhesive solution]together with the adhesive. The above capsule preferably has a particle diameter of 3W20μ, contains a melamine- formaline resin, etc. in the wall of the capsule, and is obtained by encapsulating by in-situ polymerization, etc.
