Abstract
A polymer of the formula (I): in which X1 means H or (R1)1+1—L1CO—, X2 means —(L2)m—OH or R1 means —COO−M+, —SO3−M+ or (M+)2PO32−, L1 means alkylene, arylene, aralkylene or cycloalkylene, L2 means the residue of a polyether having an average molecular weight of 200 to 3000 (number average), M+ means a cation, l means a number from 0 to 4, m means a number 0 or 1 and n means a number from 0 to 20, wherein m+n is ≧1.
Claims9

- in which
- X1 is H or (R1)l+1—CO—,
- X2 is —(L2)m—OH or
- R1 is —COO−M+, —SO3−M+ or (M+)2PO32−,
- L1 is alkylene arylene, aralkylene or cycloalkylene.
- L2 is the residue of a polyether having an average molecular weight of 200 to 3000 (number average),
- M+ is a cation,
- l is a number from 0 to 4,
- m is a number 0 or 1 and
- n is a number from 0 to 20, wherein
- m+n is ≧1.
An image-recording material which comprises a support in at least one image-forming layer and at least one-layer of the material contains a polymer is selected from the group consisting of I-1 to I-16:
