Patent ID: 7741425

Claim:
A composition comprising a) at least one polyurethane polymer of the formula (I) which is solid at room temperature and has aldimino groups in which p is an integer 1 or 2 and q is an integer 0 or 1, with the proviso that p+q=2; R 1 is either a monovalent hydrocarbon radical having 6 to 30 C atoms which optionally has at least one heteroatom; or is a substituent of the formula (II) in which R 6 is a divalent hydrocarbon radical having 2 to 20 C atoms which optionally has at least one heteroatom; and R 7 is a monovalent hydrocarbon radical having 1 to 20 C atoms; R 2 and R 3 either, independently of one another, are each a monovalent hydrocarbon radical having 1 to 12 C atoms; or together form a divalent hydrocarbon radical having 4 to 20 C atoms, which is part of an optionally substituted carbocyclic ring having 5 to 8, preferably 6, C atoms; and in which R 4 is a divalent hydrocarbon radical having 2 to 12 C atoms which optionally has at least one heteroatom; R 5 is the radical of a polyurethane polymer D which is solid at room temperature and has isocyanate groups, after removal of (p+q) isocyanate groups; X is O, S or N—R 8 , in which R 8 is either a monovalent hydrocarbon radical having 1 to 20 C atoms which optionally has at least one carboxylic acid ester, nitrile, nitro, phosphonic acid ester, sulfone or sulfonic acid ester group or a substituent of the formula (III) b) at least one polyurethane polymer P having isocyanate groups, if q in formula (I) is zero, or if X in formula (I) is N—R 8 with R 8 as a substituent of the formula (III).
