Abstract
A resin emulsion to be used in a water-based ink, wherein the resin emulsion for a water-based ink is characterized by containing emulsion particles and a carboxylic acid polymer non-metal salt and by the emulsion particles containing a polymer comprising a monomer component including a nitrogen atom-containing monomer; and a resin emulsion for a water-based ink that can be used suitably in the water-based ink and a method for producing the same.
Claims6
A resin emulsion for a water-based ink, comprising:
- (A) emulsion particles comprising a polymer made of a monomer component comprising:
- (1) a nitrogen atom-containing monomer selected from the group consisting of a piperidine monomer and a tertiary amine of a (meth)acrylate in a content of 0.5 to 10% by mass;
- and
- (2) a hydroxyl group-containing (meth)acrylate in a content of 0.5 to 30% by mass;
- and
- (B) 0.3 to 10 parts by mass of a carboxylic acid polymer non-metal salt per 100 parts by mass of a non-volatile component of the resin emulsion;
- wherein the mass ratio of the nitrogen-containing monomer to the carboxylic acid polymer non-metal salt (nitrogen-containing monomer/carboxylic acid polymer non-metal salt) in the resin emulsion is from 1:99 to 99:1.

A method for producing a resin emulsion for a water-based ink, comprising:
- (A) carrying out an emulsion-polymerization of a monomer component comprising:
- (i) a nitrogen atom-containing monomer selected from the group consisting of a piperidine monomer and a tertiary amine of a (meth)acrylate in a content of 0.5 to 10% by mass;
- and
- (ii) a hydroxyl group-containing (meth)acrylate in a content of 0.5 to 30% by mass, to give a resin emulsion comprising emulsion particles;
- and
- (B) mixing the resin emulsion with 0.3 to 10 parts by mass of a carboxylic acid polymer non-metal salt per 100 parts by mass of a non-volatile component of the resin emulsion;
- wherein the mass ratio of the nitrogen-containing monomer to the carboxylic acid polymer non-metal salt (nitrogen-containing monomer/carboxylic acid polymer non-metal salt) in the resin emulsion is from 1:99 to 99:1.
