Abstract
A curable composition can comprise a polymerizable material and an initiator. The polymerizable material can comprise a first monomer and a second monomer, wherein the second monomer is soluble in the first monomer, and the second monomer includes a ring structure selected from a maleimide ring, a pyrone ring, or a 2-furanone rings. The curable composition can have a viscosity of not greater than 10 mPa·s, a fast curing kinetic, low shrinkage during curing, and is suitable for use in inkjet adaptive planarization.

A curable composition comprising a polymerizable material and an initiator, wherein
- the polymerizable material comprises a first monomer and a second monomer, the second monomer including a ring structure selected from a maleimide-ring, a pyrone ring, or a 2-furanone ring;
- the second monomer is soluble in the first monomer, and
- the curable composition has a viscosity of not greater than 10 mPa·s.
A laminate comprising a substrate and a cured layer overlying the substrate, wherein the cured layer comprises an acrylate/maleimide copolymer;
- a total carbon content of the at cured layer is least 74%, and a weight loss of the cured layer after a heat treatment at a temperature of 250° C. for 90 seconds is not greater than 2.5% based on the total weight of the cured layer before the heat treatment.
A method of manufacturing an article comprising:
- applying a layer of a curable composition on a substrate, wherein the curable composition comprises a polymerizable material and a photoinitiator, and wherein the polymerizable material comprises a first monomer and a second monomer, the second monomer including a ring structure selected from a maleimide-ring, a pyrone ring, or a 2-furanone ring;
- the second monomer is soluble in the first monomer;
- and the curable composition has a viscosity of not greater than 10 mPa·s;
- bringing the curable composition into contact with a superstrate;
- curing the curable composition with light or heat to form a cured layer;
- removing the superstrate from the cured layer;
- and
- processing the substrate with the cured layer to make the article.
