Abstract
A photocurable composition can comprise a polymerizable material and an initiator. The polymerizable material can include at least one first multi-functional monomer containing an allyloxymethyl methacrylate structure in an amount at least 5 wt % and not greater than 20 wt % based on the polymerizable material. The photocurable composition can be suitable for use in inkjet adaptive planarization and may be adapted to form cured layers having a glass transition temperature of at least 120° C.

A photocurable composition comprising a polymerizable material and a photo-initiator, wherein the polymerizable material comprises at least one first multi-functional monomer of Formula (1) in an amount of at least 5 wt % and not greater than 20 wt % based on the total weight of the polymerizable material,
- with R being C1-C6 alkyl, alkyl-aryl, or aryl,
- and wherein the composition is adapted for forming a cured layer having a glass transition temperature of at least 120° C.
A method of forming a photo-cured layer on a substrate, comprising:
- applying a photocurable composition on a substrate, wherein the photocurable composition comprises a polymerizable material and a photo-initiator, wherein the polymerizable material comprises at least one first multi-functional monomer of Formula (1) in an amount at least 5 wt % and not greater than 20 wt % based on the total weight of the polymerizable material
- with R being C1-C6-alkyl, alkyl-aryl, or aryl;
- bringing the photocurable composition into contact with a superstrate;
- irradiating the photocurable composition with light to form a photo-cured layer, wherein the photo-cured layer has a glass-transition temperature of at least 120° C.;
- and
- removing the superstrate from the photo-cured layer.
A method of manufacturing an article, comprising:
