Abstract
A diketone oxime ester compound shown in formula I and a manufacturing method therefor, and a photo-curable composition using the compound of formula I as a photoinitiator. The composition has extremely high light sensitivity and relatively low yellowing resistance when applied to prepare a color filter for a light resistance device such as a display screen.
Claims5
A process for producing a relief pattern, comprising diluting a photo-curable composition with a solvent, coating the photo-curable composition on a substrate, drying off the solvent to obtain a coated layer, curing the coated layer by irradiating with light having a wavelength of 190-600 nm, and removing unexposed part by exposure and development methods;
- the photo-curable composition includes a compound of formula I as a photoinitator, at least one free-radically polymerizable carbon-carbon double bond compound and optionally other components, the compound of formula I in which both oxime groups are trans form,
