Patent ID: 8324340

Claim:
A one-component, moisture-curing composition comprising a) at least one polyurethane polymer P1 which is liquid at room temperature and contains isocyanate groups, and b) at least one polyurethane polymer A which is solid at room temperature, contains aldimine groups, is of the formula (I a) or (I b), and has a melting point in the range from 40° C. to 80° C. where Q is the radical of a polyurethane polymer P2, which is solid at room temperature and has a melting point in the range from 40° C. to 80° C., after removal of m+n isocyanate groups; Y 1 and Y 2 independently of one another either are each a monovalent hydrocarbon radical having 1 to 12 C atoms, or together are a divalent hydrocarbon radical having 4 to 20 C atoms which is part of an unsubstituted or substituted carbocyclic ring having 5 to 8 C atoms; Y 3 is a monovalent hydrocarbon radical which optionally contains at least one heteroatom; Y 4 is a substituted or unsubstituted aryl or heteroaryl group which has a ring size of between 5 and 8 atoms, or is where R 6 is a hydrogen atom or is an alkoxy group, or is a substituted or unsubstituted alkenyl or arylalkenyl group having at least 6 C atoms; R 1 either is a divalent hydrocarbon radical having 2 to 12 C atoms which optionally contains at least one heteroatom, or, if X is N—R 2′ , is together with R 2′ a trivalent hydrocarbon radical having 4 to 12 C atoms which optionally contains at least one heteroatom; X is O or is S or is N—R 2 or is N—R 2′ , where R 2 either is a monovalent hydrocarbon radical having 1 to 20 C atoms which optionally contains at least one carboxylic ester, nitrile, nitro, phosphonic ester, sulfonyl or sulfonic ester group, or is a substituent of the formula (II a) or (II b) and R 2′ together with R 1 is a trivalent hydrocarbon radical having 4 to 12 C atoms which optionally contains at least one heteroatom; and n is 1 or 2 or 3, m is 0 or 1 or 2, wherein m+n is 2 or 3.
