Abstract
There is provided a treatment agent applicable to a recording surface of a recording medium which is recording paper or fabric. The treatment agent contains: a non-cationic sizing agent; and at least one cationic substance which is selected from the group consisting of: a cationic polymer capable of forming a flexible film in a case that the cationic polymer is dried, a cationic surfactant, a polyvalent metal salt and a polyvalent metal ion.

A treatment agent applicable to a recording surface of a recording medium which is recording paper or fabric, the treatment agent comprising:
- a non-cationic sizing agent;
- and
- at least one cationic substance which is selected from the group consisting of:
- a cationic polymer capable of forming a flexible film in a case that the cationic polymer is dried, and a cationic surfactant,
- wherein the cationic polymer is a cationic polymer having a urethane structure or a water-soluble polymer having diallylamines represented by the following formula (2) as a constituent of the water-soluble polymer:
- wherein in the formula (2), R2 and R3 are each a substituted or non-substituted, straight-chain or branched-chain alkyl group, and the R2 and the R3 are identical with each other or different from each other;
- X− is an anion, and
- wherein a number of the constituent represented by the formula (2) in the water-soluble polymer is in a range of 5 to 1000.
A treatment agent applicable to a recording surface of a recording medium which is recording paper or fabric, the treatment agent comprising:
- a non-cationic sizing agent;
- and
- at least one cationic substance which is selected from the group consisting of:
- a cationic polymer capable of forming a flexible film in a case that the cationic polymer is dried, a cationic surfactant, a polyvalent metal salt and a polyvalent metal ion,
- wherein in a case that the recording medium is the fabric, the non-cationic sizing agent applied to the recording surface is washed by water.
