Abstract
Abstract The surfactants of this invention are phenolic-formaldehyde resins that have been sulfomethylated with from 1-13 moles of sulfomethylation per 1000 grams of the starting resin and further modified by reaction with up to 20 moles, preferably 0.25 to 10 moles, per 1000 grams of starting resin of a blocking agent of the type X(CHR)m(CH2)nY, wherein X is a halogen, an activated double bond, epoxy ring or halohydrin, Y is a property group such as sulfonate, phosphonate, carboxylate or hydroxyl, R is another property group such as hydrogen, hydroxyl, mercaptan or amine, and n and m are integers from 0 to 5, with n or m being at least 1, to at least partially block the phenolic hydroxyl group of the resin. The phenolic-formaldehyde resin may also be cross-linked to tailor its molecular weight and then treated with urea or ammonia, if desired.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
119 words
A dyestuff composition comprising, a disperse or vat dye cake and from 1 to 75% by weight of a water-soluble dispersant on said dyestuff composition, said water-soluble dispersant being reaction products of sulfomethylated phenolic-formaldehyde resin and 0.25 moles to 20 moles per 1000 grams of said resin of an agent of the type X(CHR) m (CH 2 ) n Y, wherein X is a halogen, a halohydrin group, an activated double bond or an epoxide group, Y is a sulfonate, carboxylate, phosphonate or hydroxyl, mercaptan, amine or hydrogen, and n and m are integers from 0 to 5 with m and n together being at least 1, to give resin adducts with the phenolic hydroxyl at least partially blocked.
Claim 2
Dependent Claim
119 words
A dyestuff composition comprising, a disperse or vat dye cake and from 1 to 75% by weight of a water-soluble dispersant on said dyestuff composition, said water-soluble dispersant being reaction products of sulfomethylated phenolic-formaldehyde resin and 0.25 moles to 20 moles per 1000 grams of said resin of an agent of the type X(CHR) m (CH 2 ) n Y, wherein X is a halogen, a halohydrin group, an activated double bond or an epoxide group, Y is a sulfonate, carboxylate, phosphonate or hydroxyl, mercaptan, amine or hydrogen, and n and m are integers from 0 to 5 with m and n together being at least 1, to give resin adducts with the phenolic hydroxyl at least partially blocked.
