Abstract
A sizing agent includes a vinyl copolymer having a repeating unit (i) having a quaternary amino group and a repeating unit (ii) derived from acrylic monomers having a hydrophilic polyoxyethylene, the ratio by mass, (i):(ii), of the repeating unit (i) to the repeating unit (ii) being 60:40 to 90:10. A recording sheet having the sizing agent is also provided.
Claims4
A sizing agent comprising:
- a vinyl copolymer having a repeating unit (i) represented by general formula (1) and a repeating unit (ii) represented by general formula (2), the ratio by mass, (i):(ii), of the repeating unit (i) to the repeating unit (ii) being 60:40 to 90:10:
- 5
- wherein R represents an alkyl group of 1 to 10 carbon atoms, and the alkyl group may be branched;
- 6
- wherein R′ represents an alkyl group of 1 to 10 carbon atoms, the alkyl group may be branched, and k represents a real number of 1 to 3.
