Abstract

It is an object of the present invention to provide a chlorinated polyolefin resin having favorable adhesion to a polyolefin resin and high solubility in a composition containing an alcohol-based solvent. The present invention provides a chlorinated polyolefin resin that exhibits, in infrared spectroscopy spectrum measurement, a peak area ratio A/B×100 of 10% or higher, a peak area ratio C/B×100 of 30 to 80%, and a peak area ratio A/C×100 of 30% or higher (wherein “A” is the area of a peak resulting from hydroxyl groups, “B” is the area of a peak resulting from methylene groups, and “C” is the area of a peak resulting from carbonyl groups). The present invention also provides an ink composition for gravure printing or flexography that contains the chlorinated polyolefin resin, a printed material obtained using the above composition, and a printing method using the above composition.

First claim

The invention claimed is:

1. A chlorinated polyolefin resin wherein:
the chlorinated polyolefin resin exhibits, in infrared spectroscopy spectrum measurement, a peak area ratio A/B×100 of 10% or higher,
a peak area ratio C/B×100 of 30 to 80%, and
a peak area ratio A/C×100 of 30% or higher,
wherein “A” is an area of a peak resulting from hydroxyl groups, “B” is an area of a peak resulting from methylene groups, and “C” is an area of a peak resulting from carbonyl groups; and
a content of chlorine is 10 to 50% by weight.

2. An ink composition for gravure printing, comprising the chlorinated polyolefin resin according to claim 1 .

3. An ink composition for flexography, comprising the chlorinated polyolefin resin according to claim 1 .

4. A printed material obtained by a gravure printing method using the ink composition for gravure printing according to claim 2 .

5. A printed material obtained by a flexographic printing method using the ink composition for flexography according to claim 3 .

6. A gravure printing method using the ink composition for gravure printing according to claim 2 .

7. A flexographic printing method using the ink composition for flexography according to claim 3 .
