## Abstract

A process for producing a rosin-modified phenolic resin modified with an animal or vegetable oil, which has superior properties as a vehicle for offset printing inks; and a resin composition for printing inks comprising the oil-modified and rosin-modified phenolic resin obtained by the aforesaid process as an essential ingredient.

## Claims

### Claim 1

A process for preparing a rosin modified phenolic resin modified with an animal or vegetable oil which comprises reacting in a single step (a) an animal or vegetable oil having an iodine value of 100 to 210 or containing a hydroxyl group, (d) a rosin, (e) an alcohol, and optionally, at least one of (f) acids and (g) hydrocarbon resins, at a temperature of from 100.degree. to 160.degree. C. for 1 to 9 hours and then further reacting at 200.degree. to 280.degree. C. for from 3 to 10 hours, without reacting the phenol (a) or the formaldehyde yielding substance (b), in advance.

### Claim 2

A process for preparing a rosin modified phenolic resin modified with an animal or vegetable oil which comprises at least partially esterifying at least two of the following components (d), (e), (f) and (g) which are esterifiable with each other: (d) a rosin, (e) an alcohol, (f) an acid, and (g) a hydrocarbon resin, at a temperature of 200.degree. to 260.degree. C., to form a pre-condensate (h); and reacting the pre-condensate (h) with a phenol (a), a formaldehyde-yielding substance (b) and an animal or vegetable oil having an iodine value of 100 to 210 or containing a hydroxyl group, (c) and optionally any one of said components (d), (e), (f) and (g) which was not used to prepare said pre-condensate (h).

### Claim 3

A process for preparing a rosin modified phenolic resin modified with an animal or vegetable oil which comprises reacting an animal or vegetable oil having an iodine value of 100 to 210 or containing a hydroxyl group (c) and an alcohol (e) at a temperature of from 230.degree. to 240.degree. C. to form an ester-interchange product (i) and reacting said ester-interchange product (i) with a phenol (a) and a formaldehyde-yielding substance (b) and at least one of (d) a rosin, (f) an acid and (g) a hydrocarbon resin at a temperature of 100.degree. to 160.degree. C. for from 1 to 9 hours and then at a temperature of from 200.degree. to 280.degree. C. for from 3 to 9 hours.

### Claim 4 (depends on 1)

A resin composition for printing inks, said composition comprising a rosin-modified phenolic resin modified with an animal or vegetable oil which is prepared by the process of claim 1.

### Claim 5 (depends on 2)

A resin composition for printing inks, said composition comprising a rosin-modified phenolic resin modified with an animal or vegetable oil which is prepared by the process of claim 2.

### Claim 6 (depends on 3)

A resin composition for printing inks, said composition comprising a rosin-modified phenolic resin modified with an animal or vegetable oil which is prepared by the process of claim 3.
