Use film thickness measuring device (DEKTAK (registered trademark) 3;Japanese vacuum technique (strain) manufacture) determine The film thickness of colored pattern.It shows the result in table 2.
[making of coloring film]
In the glass substrate (EAGLE 2000 of 5cm square;Corning Incorporated manufactures) on, pigmentary resin is coated with using spin-coating method After composition is so that the film thickness after baking becomes the film thickness identical with above-mentioned colored pattern afterwards, prebake 3 minutes at 100 DEG C. After letting cool, exposure machine (TME-150RSK is used;Foretell プ Us Application (strain) to manufacture), under air atmosphere, use 150mJ/cm2Exposure Amount (365nm benchmark) has carried out light irradiation.After light irradiation, baked, obtained after twenty minutes in an oven, at 150 DEG C Color film.
[contrast evaluation]
For obtained coloring film, contrast meter (CT-1 is used;Pot slope motor (strain) manufacture, color evaluating BM- 5A;Foretell the manufacture of プ U ソ Co., Ltd., light source;F-10, light polarizing film;Pot slope motor (strain) manufactures) determine contrast.It should say Bright, blank value during measure is 30000.It shows the result in table 2.
【Table 2】
Film thickness (μm) Contrast
Embodiment 1 20 27100
Embodiment 2 20 22100
Comparative example 1 20 8200
The contrast of coloring film that the colored resin composition using embodiment identified above obtains is high.Thus may be used Know, coloring film, the colored pattern obtained by the colored resin composition of the present invention can be used as colour filter, include the colour filter The display characteristic of display device is excellent, the camera shooting excellent of the solid-state imager comprising the colour filter.
Industrial availability
Colored curable resin composition using the present invention, being capable of the high colour filter of degree of being contrasted.
