Copolymer latex constituent, constituent and coating paper for paper coating

摘要

It is superior in the coating operability, at the same time, it offers the copolymer latex constituent for the paper coating which can obtain the coating paper which is superior in printability such as white paper gloss, print gloss, ink dry Characteristic and surface strength. (A) (a) aliphatic conjugate diene monomer 30 - 90 weight %, (b) ethylenic unsaturated carboxylic acid monomer 10 - 50 weight %, and (c) description above (a) - (b) the component and copolymerization possible other vinyl monomer 0 - 60 weight % (and others emulsifying polymerization the monomer component which becomes the copolymer latex which can, and (B) (d) aliphatic conjugate diene monomer 20 - 80 weight %, (e) ethylenic unsaturated carboxylic acid monomer 0.1 - 9 weight %, and (f) description above (d) - (e) the component and copolymerization possible other vinyl monomer 10 - 79.9 weight %Emulsifying polymerization the monomer component which consists of the copolymer latex which can, containing, it is the copolymer latex constituent which becomes, at the same time description above (A) the copolymer latex and (B) the copolymer latex constituent where weight ratio of the copolymer latex is the range of the 0.2:99.8 - the 30:70.
