Comparative example 1
This comparative example 1 differs from example 2 in that: the hydrophilic polyisocyanate curing agent is replaced with an aziridine-based curing agent.

This comparative example 2 differs from example 2 in that: the proportion of the hydrophilic polyisocyanate curing agent was changed to 2%.
When the aqueous gravure leather varnish prepared in comparative example 1 was applied to leather according to the application method, the problem of too fast agglomeration occurred and the phenomenon of uneven gravure occurred. When the aqueous gravure leather gloss oil prepared in comparative example 2 was applied to leather according to the application method, the ink layer became soft after gravure printing and the problem of anti-sticking was easily occurred, as shown in fig. 2.
The water-based gravure leather gloss oil prepared in example 2 is applied to leather according to a using method, and as a hydrophilic polyisocyanate curing agent is selected and a reasonable dosage is set, gravure is uniform, and the problem of anti-sticking does not exist, as shown in fig. 1. The inventors analysis should be: the amount of the added hydrophilic polyisocyanate curing agent is small, and the hydrophilic polyisocyanate curing agent can react with PUA in the formula without residue, so that the problems cannot be caused.
The above-mentioned embodiments only express the embodiments of the present invention, and the description is more specific and detailed, but not understood as the limitation of the patent scope of the present invention, but all the technical solutions obtained by using the equivalent substitution or the equivalent transformation should fall within the protection scope of the present invention.
