Abstract

A resin containing oxetane and epoxy groups is provided, being formed by reacting (a) a product of reacting 1 part by mole of a mono-oxetane with a hydroxyl group and 1.1 to 2.5 parts by mole of anhydride, and (b) 2.1 to 4.2 parts by mole of a diepoxy compound. The mono-oxetane with a hydroxyl group has a structure:

wherein R 1 is H, C 1-6 alkyl group, C 1-6 fluoroalkyl group, alkenyl group, or phenyl group, and R 2 is C 1-6 alkylene group or vinyl ether group.

First claim

What is claimed is:

1. A resin composition, comprising:
100 parts by weight of a resin; and
1 to 10 parts by weight of a curing agent, wherein the curing agent comprises a UV cationic initiator, thermal cationic initiator, or thermal anionic initiator,
wherein the resin is formed by reacting:
(a) a product of reacting 1 part by mole of a mono-oxetane with a hydroxyl group and 1.1 to 2.5 parts by mole of anhydride, and
(b) 2.1 to 4.2 parts by mole of a diepoxy compound.

2. The resin composition as claimed in claim 1 , wherein the diepoxy compound is

or a combination thereof;
wherein R 5 is

wherein z1 is an integer of 0 to 3;
R 6 is

wherein z2 is a positive integer of 1 to 4.

3. The resin composition as claimed in claim 1 , wherein the resin has a viscosity of 50 Pa·s to 1,100 Pa·s at room temperature.

4. The resin composition as claimed in claim 1 , further comprising 0.1 to 30 parts by weight of an additive.

5. The resin composition as claimed in claim 4 , wherein the additive comprises filler, defoamer, leveling agent, or a combination thereof.

6. The resin composition as claimed in claim 1 , wherein the mono-oxetane with a hydroxyl group has a structure:

wherein R 1 is H, C 1-6 alkyl group, C 1-6 fluoroalkyl group, alkenyl group, or phenyl group,
and
R 2 is C1-6 alkylene group or vinyl ether group.

7. The resin composition as claimed in claim 1 , wherein the mono-oxetane with a hydroxyl group has a structure:

8. The resin composition as claimed in claim 1 , wherein the anhydride has a structure:

wherein R 3 is

or a combination thereof,
each R 4 is independently of H, C 1-16 alkyl group, or C 1-16 alkyl group where a —CH 2 group is substituted by oxygen, ethylene group, carbonyl group, carboxyl group, cyclohexyl group, or phenyl group;
wherein

9. The resin composition as claimed in claim 1 , wherein the anhydride has a structure:

10. The resin composition as claimed in claim 1 , wherein the diepoxy compound is

11. The resin composition as claimed in claim 1 , being:

or a combination thereof,
wherein R 1 is H, C 1-6 alkyl group, C 1-6 fluoroalkyl group, alkenyl group, or phenyl group;
R 2 is C 1-6 alkylene group or vinyl ether group;
R 3 is

or a combination thereof,
each R 4 is independently of H, C 1-16 alkyl group, or C 1-16 alkyl group where a —CH 2 group is substituted by oxygen, ethylene group, carbonyl group, carboxyl group, cyclohexyl group, or phenyl group;

R 5 is

R 6 is

wherein z1 is an integer of 0 to 3, z2 is a positive integer of 1 to 4, m1 is a positive integer greater than 1, n1 is a positive integer greater than 1, m2 is a positive integer greater than 1, and n2 is a positive integer greater than 1.
