Abstract

Abstract Colorants and compositions useful as a fugitive or permanent colorant for a variety of substrates, or as intermediates for their manufacture, and having one or more improved properties of enhanced aqueous washability, compatibility with and non-extractibility from thermoplastic resins, or reactivity with resins having reactive functionality, said composition having the formula C(Z) 1-8 wherein: C is the residue of a reactant having from 1-8 nucleophilic site residues to which the Z moieties are attached; said Z moieties containing at least about 60 weight percent of poly(oxyalkylene) which is comprised of (a) at least one glycidol residue segment of 2-6 glycidol residues attached to a nucleophilic site of C, wherein said poly(oxyalkylene) contains a total of from 2-20 glycidol residues, (b) and wherein said poly(oxyalkylene) further contains the residues of one or more other epoxide reactants of ethylene oxide (EO), propylene oxide (PO), or butylene oxide (BO), or mixtures thereof, wherein said poly(oxyalkylene) contains a total of from about 10 to about 600 of said EO, PO or BO residues, or mixtures thereof, at least about 75 mole percent of which are EO residues, (c) and with the provisions that the ratio of the total of --0--PO-- and --O--BO-- linkages of all glycidol residues to the total of all functional oxy linkages of said glycidol residues is less than one, and the molar ratio of EO residues to glycidol residues is from 4 to 75.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 150 words
A colorant comprising a compound having the formula C(Z) 1-8 wherein: C is a chromogen radical having from 1-8 nucleophilic site residues to which the Z moieties are attached; said Z moieties containing at least about 60 weight percent of poly(oxyalkylene) which is comprised of (a) at least one glycidol residue segment of 2-6 glycidol residues attached to a nucleophilic site of C, wherein said poly(oxyalkylene) contains a total of from 2-20 glycidol residues, and (b) wherein said poly(oxyalkylene) further contains three separate poly (oxyalkylene) branches pendant from said glycidol residue segment containing the residues of one or more other epoxide reactants of ethylene oxide (EO), propylene oxide (PO), or butylene oxide (BO), or mixtures thereof, wherein said poly(oxyalkylene) contains a total of from about 10 to about 600 of said EO, PO or BO residues, or mixtures thereof, at least about 75 mole percent of which are EO residues.
Claim 2
Dependent Claim 150 words
A colorant comprising a compound having the formula C(Z) 1-8 wherein: C is a chromogen radical having from 1-8 nucleophilic site residues to which the Z moieties are attached; said Z moieties containing at least about 60 weight percent of poly(oxyalkylene) which is comprised of (a) at least one glycidol residue segment of 2-6 glycidol residues attached to a nucleophilic site of C, wherein said poly(oxyalkylene) contains a total of from 2-20 glycidol residues, and (b) wherein said poly(oxyalkylene) further contains three separate poly (oxyalkylene) branches pendant from said glycidol residue segment containing the residues of one or more other epoxide reactants of ethylene oxide (EO), propylene oxide (PO), or butylene oxide (BO), or mixtures thereof, wherein said poly(oxyalkylene) contains a total of from about 10 to about 600 of said EO, PO or BO residues, or mixtures thereof, at least about 75 mole percent of which are EO residues.
Claim 3
Dependent Claim 50 words
The colorant of claim 1 wherein the total number of said other epoxide residues is from about 150 to about 400 and the ratio of the total of --O--PO--AND --O--BO--linkages of all glycidol residues to the total of all functional oxy linkages of said glycidol residues is less than one.
Claim 4
Dependent Claim 22 words
The colorant of claim 1 wherein the EO residues comprise from about 90 to 100 mole percent of said other epoxide residues.
Claim 5
Dependent Claim 18 words
The colorant of claim 1 wherein the poly(oxyalkylene) moiety contains one glycidol residue segment containing 2-6 glycidol residues.
Claim 6
Dependent Claim 29 words
The colorant of claim 1 wherein each said poly(oxyalkylene) moiety is independently terminated by hydrogen or a group selected from acyl or unsubstituted or substituted alkyl, cycloalkyl, or aryl.
Claim 7
Dependent Claim 14 words
The colorant of claim 1 wherein each said poly(oxyalkylene) branch is terminated by hydrogen.
Claim 8
Dependent Claim 14 words
The colorant of claim 1 wherein the number of Z moieties is from 1-4.
Claim 9
Dependent Claim 31 words
The colorant of claim 1 wherein C is selected from compounds containing at least one chromogen radical selected from mono-, bis-, tris-, or tetrakis-azo, methine, azamethine, indophenol, or triphenylmethane chromogen radicals.
