PURPOSE: To provide a latex having good film-forming, antistatic, and adhesive properties, comprising a vinyl polymer, an anionic emulsifier, a specific amphoteric polymer, and a cationic antistatic agent. n CONSTITUTION: The objective latex can be obtained by emulsion polymerization of a vinyl monomer in an aqueous medium containing (A) 0.1W15 parts by wt. of an amphoteric polymer prepared by modification, with an agent selected from a monohalogenated acetate of formula II, an amino acid salt, and sultone, of the N of a (co)polymer composed of 10,000W100,000 constituents of formula I [R 1 is H or CH 3 ; R 2 and R 3 are each 1W4C alkyl; Z is 2W6C alkylene; X is Cl, Br, or I; M is NH 4 , an organic amine salt, or an alkali (or alkaline earth) metal], (B) 0.1W10 parts by wt. of an anionic emulsifier such as sodium stearate, sodium lauryl alcohol sulfuric ester, etc., and (C) 0W13.5 parts by wt. of a cationic polymeric antistatic agent having 10,000W100,000 constituents of formula III, IV, etc. n COPYRIGHT: (C)1980,JPO&Japio |
