Aqueous Alkyd Resin Emulsion for Fixing Water-Soluble Dyes

A process for preparing a resin which comprises preparing a composition comprising at least the following components:

• at least one polyhydric alcohol having at least two hydroxyl groups,
• at least one polyetherpolyol having a molecular weight of 400 to 8000 g/mol,
• at least one monobasic carboxylic acid, and
• at least one polybasic carboxylic acid having at least two carboxyl groups or its anhydride,
• converting the composition to a resin, and modifying the resin by introduction of at least one basic group.

A process for preparing a resin comprising reacting a composition comprising:

• at least one polyhydric alcohol having at least two hydroxyl groups,
• at least one polyetherpolyol having a molecular weight of 400 to 8000 g/mol,
• at least one monobasic carboxylic acid, and
• at least one polybasic carboxylic acid having at least two carboxyl groups or its anhydride,
• with a compound comprising at least one basic group, and at least one reactive group capable of reacting with a group on the resin to form a covalent bond.
