Abstract
Abstract A process is provided for coloring thermosetting resins, made by polyaddition reaction of a nucleophile with an electrophile, with a polymeric liquid reactive coloring agent suitable for incorporation in the resin with the formation of covalent bonds, said coloring agent having the formula: R-(polymeric constituent-X).sub.n wherein R is an organic dyestuff radical; the polymeric constituent is selected from polyalkylene oxides and copolymers of polyalkylene oxides in which the alkylene moiety of the polymeric constituent contains 2 or more carbon atoms and such polyeric constituent has a molecular weight of from about 44 to about 1500; and n is an integer of from 1 to about 6; and X is selected from --OH, --NH 2 and --SH, said coloring agent being added in an amount sufficient to provide coloration of said thermosetting resin.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
175 words
A process for coloring thermosetting resins, made by the polyaddition reaction in a reaction mixture of a nucleophile with an electrophile, which comprises adding to the reaction mixture before or during the polyaddition reaction a polymeric liquid reactive coloring agent suitable for incorporation in the resin with the formation of covalent bonds, said coloring agent having the formula: R-(polymeric constituent-X).sub.n wherein R is an organic dyestuff radical; the polymeric constituent is selected from polyalkylene oxides and copolymers of polyalkylene oxides in which the alkylene moiety of the polymeric constituent contains 2 or more carbon atoms and such polymeric constituent has a molecular weight of from about 44 to about 1500; and n is an integer of from 1 to about 6; and X is selected from --OH, --NH 2 and --SH, wherein the organic dyestuff radical and polymeric constituent are selected so as to provide said coloring agent in the liquid phase at ambient conditions of temperature and pressure; said coloring agent being added in an amount sufficient to provide coloration of said thermosetting resin.
Claim 2
Dependent Claim
175 words
A process for coloring thermosetting resins, made by the polyaddition reaction in a reaction mixture of a nucleophile with an electrophile, which comprises adding to the reaction mixture before or during the polyaddition reaction a polymeric liquid reactive coloring agent suitable for incorporation in the resin with the formation of covalent bonds, said coloring agent having the formula: R-(polymeric constituent-X).sub.n wherein R is an organic dyestuff radical; the polymeric constituent is selected from polyalkylene oxides and copolymers of polyalkylene oxides in which the alkylene moiety of the polymeric constituent contains 2 or more carbon atoms and such polymeric constituent has a molecular weight of from about 44 to about 1500; and n is an integer of from 1 to about 6; and X is selected from --OH, --NH 2 and --SH, wherein the organic dyestuff radical and polymeric constituent are selected so as to provide said coloring agent in the liquid phase at ambient conditions of temperature and pressure; said coloring agent being added in an amount sufficient to provide coloration of said thermosetting resin.
