| 摘要 | PURPOSE: To improve adhesiveness without impairing discoloration-time control capacity, by using a polymer obtained by polymerizing a polyfunctional vinyl monomer with an acrylic ester monomer as a discoloration-time control layer. CONSTITUTION: A discoloration-time control layer is obtained by applying a crosslinkable acrylic emulsion obtained by polymerizing a (meth)acrylic ester monomer and a polyfunctional vinyl monomer as essential components and drying the same. Concretely, this discoloration-time control layer is provided between the A-layer containing a microcapsule of an oily substance and B-layer containing a substance generating discoloration upon the contact with the component in the microcapsule provided on a support. As mentioned above, by using the polymer obtained by copolymerizing the acrylic ester monomer and the polyfunctional monomer, adhesiveness can be improved without impairing discoloration-time control capacity.
