Abstract

Polyallylamine derivatives including 10 to 450 structural units represented by Formula (1):

are useful for preparing dispersants, treated particles, particle-containing compositions, pigment-containing compositions, paints, ink compositions, liquid developers, and anti-blocking agents.

First claim

The invention claimed is:

1. A polyallylamine derivative, comprising 10 to 450 structural units represented by Formula (1):

wherein in Formula (1), A 1 represents a group represented by Formula (2), Formula (3), Formula (4), or Formula (5), and a plurality of said A 1 s are optionally the same as or different from each other; with the proviso that at least one of said A 1 s is a group represented by Formula (4) or Formula (5):

wherein in Formulae (2) and (3), R 1 represents an alkylene group optionally having a substituent, an alkenylene group optionally having a substituent, or an alkylene group having an ether bond optionally having a substituent; a represents an integer of 0 to 100; a plurality of said R 1 s are the same as or different from each other;
in Formulae (4) and (5), R 1 represents an alkylene group optionally having a substituent, an alkenylene group optionally having a substituent, or alkylene group having an ether bond optionally having a substituent; R 2 represents an alkyl group optionally having a substituent, an alkenyl group optionally having a substituent, or an alkyl group having an ether bond optionally having a substituent; a represents an integer of 0 to 100; and a plurality of said R 1 s are the same as or different from each other,
wherein N R2 /(N R1 +N R2 )×100 is 1 to 35 where N R1 is an average number of moles of R 1 present in the molecules of the polyallylamine derivative and N R2 is an average number of moles of R 2 present in the molecules of the polyallylamine derivative.

2. The polyallylamine derivative according to claim 1 , wherein the polyallylamine derivative has a side chain mass/main chain mass ratio of 6 to 28.

3. The polyallylamine derivative according to claim 1 , which has an amine value of 5 mg KOH/g to 150 mg KOH/g.

4. The polyallylamine derivative according claim 1 , wherein R 1 comprises a branched alkylene group having 6 to 30 carbon atoms optionally having a substituent.

5. The polyallylamine derivative according to claim 1 , wherein R 2 comprises an alkyl group having 10 to 20 carbon atoms optionally having a substituent or an alkenyl group having 2 to 30 carbon atoms optionally having a substituent.

6. The polyallylamine derivative according to claim 1 , which has an acid value of 1 mg KOH/g to 10 mg KOH/g.

7. A dispersant, comprising a polyallylamine derivative according to claim 1 .

8. Treated particles treated with a dispersant according to claim 7 .

9. A particle-containing composition, comprising a polyallylamine derivative according to claim 1 and particles.

10. A paint, comprising a particle-containing composition according to claim 9 .

11. An ink composition, comprising a particle-containing composition according to claim 9 .

12. A liquid developer, comprising a particle-containing composition according to claim 9 .

13. An anti-blocking agent, comprising a particle-containing composition according to claim 9 .
