摘要： The water-base coating formulation comprises as essential components (a) microcapsules which have a synthetic resin as a wall-forming material and (b) a reaction product obtained by polymerizing at least one water-soluble vinyl monomer (B) in the presence of a high polymer latex (A) having a glass transition point of 60°C or lower. The latex (A) and vinyl monomer (B) are used at a solid weight ratio of 3:97 - 90:10. The coating formulation can provide a microcapsule-coated layer having significantly-improved pressure resistance and frictional stability without need for a stilt, and can be applied successfully at a high speed. The coating formulation can form the basis of carbonless copying and/or recording paper for instance of self-contained character incorporating both a dye precursor and a color developer.
