experiment example

[0262] The compositions in Tables 1 and 2, or coating films formed from these compositions, and photocured films were evaluated for coatability, Martens hardness, indentation modulus, and oxygen inhibition by the evaluation methods described later. The evaluation results are shown in Table 3 below.

[0263] (1) Coatability evaluation

[0264] Each composition of the Examples and Comparative Examples was spin-coated on a silicon (Si) sheet cut into a size of 50 mm×50 mm to form a coating film so as to have a thickness of 3.0 μm. After spin coating, it was left to stand for 5 minutes, the shape of the coating film was observed, and applicability was evaluated as follows.

[0265]

[0266] ○: The coating film is spread evenly and has a uniform surface (see Figure 4 )

[0267] △: Although the composition was developed, surface unevenness was observed with the naked eye (see Figure 5 )

[0268] ×: The surface is not wetted but the liquid dries and the coating film is not...

Abstract

The present invention provides a photocurable composition containing a bifunctional or higher allyl ether compound, a monofunctional to trifunctional hydrocarbon-based (methyl) compound, and a photocurable film formed from the photocurable composition. Acrylate compounds, silicone-based (meth)acrylate compounds, carboxylic acid-containing monomers, and photoinitiators. Through the interaction of the allyl ether compound and the (meth)acrylate compound, a composition and a photocurable film having low viscosity, improved reactivity, hardness, and flexibility can be realized.

Description

technical field [0001] The present invention relates to a photocurable composition and a photocurable film formed from the photocurable composition. More specifically, it relates to a photocurable composition containing a photopolymerizable monomer, and a photocurable film formed from the photocurable composition. Background technique [0002] In order to form various photocurable insulating patterns such as photoresists, insulating films, protective films, black matrices, and columnar spacers of display devices, photosensitive compositions are used. After applying the above-mentioned photosensitive composition, a photocured pattern of a predetermined shape can be formed in a desired region through an exposure step and / or a development step. The above-mentioned photosensitive composition needs to have, for example, high sensitivity to ultraviolet light exposure and polymerization reactivity, and the pattern formed from the photosensitive composition needs to have improved h...
