Abstract
Abstract A process for coloring polyurethane resins made by a polyaddition reaction of a polyol and an isocyanate is provided, which comprises adding to the reaction mixture before or during the polyaddition reaction a reactive coloring agent suitable for incorporation in the resin with the formation of covalent bonds, said coloring agent having the formula: <CHEM> in which R1 and R2 are independently selected from an alkyl group having from 1 to about 12 carbon atoms, X is --CH2--, a and a min are integers from 1 to about 6, and Y and Y min are independently selected from polymeric units of hydroxy alkylenes or alkylene oxide monomers selected from ethylene oxide, propylene oxide, butylene oxide, cyclohexene oxide, or glycidol, b and b min are independently either 0 or 1, and Z and Z min are reactive groups independently selected from -OH, -NH2, or -SH.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
144 words
A process for coloring polyurethane resins made by a polyaddition reaction of a polyol and an isocyanate, which comprises adding to the reaction mixture before or during the polyaddition reaction a reactive coloring agent suitable for incorporation in the resin with the formation of covalent bonds, said coloring agent having the formula: ##STR6## in which R 1 and R 2 are independently selected from an alkyl group having from 1 to about 12 carbon atoms, X is --CH 2 --, a and a' are integers from 1 to about 6, and Y and Y' are independently selected from polymeric units of hydroxy alkylenes or alkylene oxide monomers selected from ethylene oxide, propylene oxide, butylene oxide, cyclohexene oxide, or glycidol, b and b' are independently either 0 or 1, and Z and Z' are reactive groups independently selected from --OH, --NH 2 , or --SH.
Claim 2
Dependent Claim
144 words
A process for coloring polyurethane resins made by a polyaddition reaction of a polyol and an isocyanate, which comprises adding to the reaction mixture before or during the polyaddition reaction a reactive coloring agent suitable for incorporation in the resin with the formation of covalent bonds, said coloring agent having the formula: ##STR6## in which R 1 and R 2 are independently selected from an alkyl group having from 1 to about 12 carbon atoms, X is --CH 2 --, a and a' are integers from 1 to about 6, and Y and Y' are independently selected from polymeric units of hydroxy alkylenes or alkylene oxide monomers selected from ethylene oxide, propylene oxide, butylene oxide, cyclohexene oxide, or glycidol, b and b' are independently either 0 or 1, and Z and Z' are reactive groups independently selected from --OH, --NH 2 , or --SH.
