Problems solved by technology

[0003] However, generally rigid photocurable resins are mostly molecules with aromatic groups, which are prone to slight electron transfer due to temperature and time, which will cause the composition to yellow, resulting in poor temperature resistance and weather resistance.
During processing or use and long-term storage after product output, it is easy to affect the appearance and properties of the product due to yellowing, thereby affecting product quality

Abstract

The invention provides a curable resin, which is characterized by being represented by a formula (1) 'DDA 0000809314250000011. TIF 'wi = '1454 'he = '414', wherein at least one of R1, R2 and R3 is shown as img file = 'DDA 0000809314250000012. TIF 'wi = '471 'he = '391'; R4 contains a C1-C4 alkyl group, a C1-C4 alkenyl group, a C4-C6 cycloalkyl group, a C4-C6 cycloalkenyl group or a phenyl group; R5 represents an acrylate derivative (acrylate derivatives), wherein the acrylate derivative comprises at least two functional groups.

Description

technical field [0001] The invention relates to a curable resin and a curable composition using the same, and in particular to a curable resin with multiple crosslinking reactive groups and a curable composition using the same. Background technique [0002] Optical components need to take into account both optical performance and application properties, so an anti-wear and scratch-resistant hardened protective coating must be coated on the outer layer. Generally speaking, light-curable resins are often used as surface protection coatings for optoelectronics, people's livelihood, IC and other products. This is due to the fast curing speed of light-curable resins, which can effectively improve production efficiency while saving energy consumption and reducing the production of volatile organic components. [0003] However, generally rigid photocurable resins are mostly molecules with aromatic groups, which are prone to slight electron transfer due to temperature and time, whic...
