ABSTRACT:
A microcapsule-containing water-base coating formulation comprises as essential components (a) microcapsules making use of 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.degree. C. or lower. The latex (A) and vinyl monomer (B) are used at a solid weight ratio of 3:97-90:10. The water-base coating formulation can provide a microcapsule-coated layer having significantly-improved pressure resistance and frictional stability without need for a stilt. The water-base coating formulation can be applied at a high speed, thereby making a significant improvement to the productivity of carbonless copying and/or recording paper.
