Abstract

Described is a resinous article of manufacture that is wrinkle-resistant and is warpage-resistant when subjected to very high temperatures. Such an article is useful as an optical lens.

First claim

What is claimed is:

1. A method for manufacturing a component, the method comprising:
preparing a first precursor bearing a first alkyl group and at least two polymerizable (meth)acryloyloxy substituents attached to the first alkyl group, wherein the first alkyl group includes at least one first cyclic moiety being tricyclodecane;
preparing a second precursor bearing a second alkyl group and two substituents, wherein the second alkyl group includes at least one second cyclic moiety being cyclohexane or dicyclopentane, and the two substituents include —NH—C(═O)—O—CH 2 CH 2 —O— group and an acryloyl group;
preparing a composition comprising at least the first precursor and the second precursor; and
forming a resin by curing the composition in a state in which the composition is sandwiched between a first member and a second member.

2. The method according to claim 1 , wherein the resin constitutes the component.

3. The method according to claim 1 , wherein the first alkyl group includes two cyclic moieties.

4. The method according to claim 1 , wherein the first alkyl group is a bicyclic alkyl group.

5. The method according to claim 1 , wherein the second precursor is an urethane acrylate.

6. The method according to claim 1 , wherein the resin is formed such that the resin does not have wrinkles of which the average gap is greater than or equal to 300 μm.

7. The method according to claim 1 , wherein the resin has a property that no warpage of which gap is greater than or equal to 1 mm occurs by heating the resin at 373 K for 16 hours.

8. The method according to claim 1 , wherein the component has a property that no warpage of which gap is greater than or equal to 1 mm occurs by heating the component at 373 K for 16 hours.

9. A component comprising:
a resin that includes a first alkyl group, a second alkyl group, and at least one —NH—C(═O)—O—CH 2 CH 2 —O—C(═O)—, wherein:
the first alkyl group includes at least one first cyclic moiety that is tricyclodecane, and
the second alkyl group includes at least one second cyclic moiety that is cyclohexane or dicyclopentane.

10. The component of claim 9 , wherein the first alkyl group has at least two cyclic moieties.

11. The component of claim 9 , wherein the component is a lens.

12. The component of claim 9 , wherein the component has no wrinkles of which average gap is greater than or equal to 300 μm.

13. A composition for forming a resin, the composition comprising:
a first precursor bearing a first alkyl group and at least two polymerizable (meth)acryloyloxy substituents attached to the first alkyl group, wherein the first alkyl group includes at least one first cyclic moiety being tricyclodecane; and
a second precursor bearing a second alkyl group and two substituents, wherein:
the second alkyl group includes at least one second cyclic moiety being cyclohexane or dicyclopentane, and
the two substituents each include —NH—C(═O)—O—CH 2 CH 2 —O— group and an acryloyl group.

14. The composition of claim 13 , wherein the first alkyl group includes at least two cyclic moieties.

15. The composition of claim 13 , wherein the first alkyl group is a bicyclic alkyl group.

16. The composition according to claim 13 , wherein the second precursor is an urethane acrylate.

17. The composition of claim 13 , wherein each of the first alkyl group and the second alkyl group is a bicyclic alkyl group.

18. A resin, comprising:
a first cyclic alkyl group that includes at least one first cyclic moiety that is tricyclodecane;
a second cyclic alkyl group that includes at least one second cyclic moiety that is cyclohexane or dicyclopentane; and
at least one —NH—C(═O)—O—CH 2 CH 2 —O—O—C(═O)— bond,
wherein the resin has a pencil hardness of less than or equal to 2 H, and the resin is obtained by curing the composition of claim 13 .
