Abstract
A cationizing agent for cationizing a cloth prior to the firm fixing of water-insoluble particles onto the cloth, said cationizing agent comprising a polymer having a constituent unit (a1) derived from a vinylamine monomer represented by formula (1). (In the formula, R1 represents a hydrogen atom or a methyl group.)
Claims7
A method for firmly fixing water-insoluble particles onto a fabric, comprising:
- cationizing the fabric by firmly fixing a cationizing agent to the fabric, wherein the cationizing agent comprises a polymer comprising a constituent unit (a1) derived from a vinylamine monomer represented by formula (1);
- and
- firmly fixing water-insoluble particles to the fabric by bringing the water-insoluble particles into contact with the fabric after the cationizing
- where R1 represents a hydrogen atom or a methyl group.

A method for producing a dyed material, comprising:
- cationizing a fabric by firmly fixing a cationizing agent to the fabric, wherein the cationizing agent comprises a polymer comprising a constituent unit (a1) derived from a vinylamine monomer represented by formula (1);
- and
- firmly fixing a pigment to the fabric to dye the fabric, by bringing the pigment into contact with the fabric after the cationizing
- where R1 represents a hydrogen atom or a methyl group.
