Abstract
Abstract A heat-set type printing ink comprising as the vehicle a non-aqueous dispersion prepared by dissolving a resin in a hydrocarbon solvent-containing solvent boiling at not lower than 170 DEG C. to form a resin solution and polymerizing at least one kind of vinyl monomer in said resin solution to obtain a non-aqueous dispersion. In one embodiment, the thus obtained non-aqueous dispersion may be incorporated with a resin to obtain a modified non-aqueous dispersion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
68 words
A heat-set type printing ink comprising as the vehicle a non-aqueous dispersion prepared by dissolving at least one member selected from the group consisting of petroleum resins, modified rosin resins and alkyd resins in a hydrocarbon solvent-containing solvent boiling at not lower than 170° C. to form a resin solution and polymerizing at least one kind of vinyl monomer in said resin solution to obtain the non-aqueous dispersion.
Claim 2
Dependent Claim
68 words
A heat-set type printing ink comprising as the vehicle a non-aqueous dispersion prepared by dissolving at least one member selected from the group consisting of petroleum resins, modified rosin resins and alkyd resins in a hydrocarbon solvent-containing solvent boiling at not lower than 170° C. to form a resin solution and polymerizing at least one kind of vinyl monomer in said resin solution to obtain the non-aqueous dispersion.
Claim 3
Dependent Claim
39 words
A heat-set type printing ink according to claim 1, wherein the hydrocarbon solvent is a paraffinic hydrocarbon solvent and the paraffinic hydrocarbon solvent is contained in an amount by weight of at least 50% of the hydrocarbon solvent-containing solvent.
Claim 4
Dependent Claim
50 words
A heat-set type printing ink according to claim 1, wherein said at least one kind of vinyl monomer is a vinyl monomer mixture containing at least one styrene type monomer selected from the group consisting of styrene, vinyltoluene and α-methylstyrene in an amount by weight of 30-95% of the mixture.
Claim 5
Dependent Claim
36 words
A heat-set type printing ink according to claim 1, wherein said at least one kind of vinyl monomer is used in an amount by weight of 20-200 parts per 100 parts by weight of the resin.
Claim 6
Dependent Claim
91 words
A heat-set type printing ink comprising as the vehicle a final non-aqueous dispersion prepared by dissolving 20 to less than 100 parts by weight of a resin in 100-200 parts by weight of a hydrocarbon solvent-containing solvent to form a solution, polymerizing 20-200 parts by weight of at least one kind of vinyl monomer in the thus formed solution to obtain a non-aqueous dispersion and then adding up to 80 parts by weight of a resin, the resins used totalling 100 parts by weight, thereby to obtain the final non-aqueous dispersion.
Claim 7
Dependent Claim
91 words
A heat-set type printing ink comprising as the vehicle a final non-aqueous dispersion prepared by dissolving 20 to less than 100 parts by weight of a resin in 100-200 parts by weight of a hydrocarbon solvent-containing solvent to form a solution, polymerizing 20-200 parts by weight of at least one kind of vinyl monomer in the thus formed solution to obtain a non-aqueous dispersion and then adding up to 80 parts by weight of a resin, the resins used totalling 100 parts by weight, thereby to obtain the final non-aqueous dispersion.
