摘要： A synthetic resin emulsion whose polymer particles are solid core-shell particles in which form pores spontaneously upon drying is produced by the steps of preparing as core particles from 2 to 60 parts by weight of polymer (A) by emulsion polymerization of from 10 to 80 parts by weight of acrylate ester (a.sub.1) having an alkyl group of from 1 to 3 carbon atoms and from 90 to 20 parts by weight another of vinyl-type monomer (a.sub.2) copolymerizable therewith, forming a shell of a polymer (B) on the surface of the core particles of polymer (A) by emulsion polymerization in the presence thereof of from 98 to 40 parts by weight of vinyl-type monomer (b), different from polymer (a.sub.1) and successively hydrolyzing the core portion of the particles with an alkaline material. Organic pigments prepared from the synthetic resin emulsion can improve the hiding power, brightness, gloss and other properties of articles coated therewith.

摘要： A heat-sensitive recording material wherein a copolymer emulsion is employed, the copolymer emulsion being obtained by copolymerizing a monomer component which comprises (meth)acrylamide and an optional unsaturated monomer component copolymerizable with (meth)acrylamide in the presence of a seed emulsion serving as a nucleating particle. In the heat-sensitive recording material, the intermediate layer, the heat-sensitive recording layer or the protective layer comprises the copolymer emulsion. The recordinq layer and the resulting recorded images of such a heat-sensitive recording material have sufficient durability (such as water resistance, heat resistance, resistance to plasticizers and resistance to solvents) and the resistance to heat softening of the protective layer. The heat-sensitive recording material can be produced through easy process control and is excellent in color developing sensitivity.
