Experimental example 1
By spin-coating method, the every kind of coloring phototonus resin that will be prepared respectively in embodiment and comparative example at a certain angle
After composition is coated on 2 inches of glass substrate (being manufactured by Corning Co., EAGLE XG), by coated substrate
Placement is kept for 3 minutes on hot plate and at a temperature of being retained in 100 DEG C, to form film.Then, will have 1% to
The pattern of the light transmittance of stepped change and size are the test light of 1 μm to 50 μm of lines/space pattern in the range of 100%
Mask is placed on the thin film, then apart from the progress UV radiation of 100 μm of test photomask place.Here, for UV radiation
Light source is 1KW high-pressure mercury (Hg) lamp, and the high-pressure sodium lamp contains all g rays, h rays and i rays, and with 100mJ/cm2
Radiation intensity light.The film radiated by UV is immersed in the KOH developer solutions that pH value is 10.5, continues 2 minutes, from
It is and developed.After the glass substrate of film is scribbled using distilled water flushing, by being blown into nitrogen to the glass substrate to make
It is dried, and is then heated 25 minutes in 200 DEG C of oven heat.So as to form colour filter.Above-mentioned formed colour filter utensil
There is 2.0 μm of film thickness.
(1) sticky assessment
The pattern formed by observation by light microscope, commented according to the following standard that (picking) is picked up for pattern
Estimate pattern pickup.Evaluation result is as shown in table 1.
○：Do not observe that pattern picks up
△：1 to 3 pattern pickup
X：The pattern pickup of 4 or more
(2) measurement of developing powder
Measure until non-exposed portion is completely dissolved the required time during development, measurement result is as shown in table 1.
Experimental example 2
In addition to no photomask used for test, formed according to the same steps described in experimental example 1
Colour filter.
(1) change and the aberration of contrast are measured
The substrate of the colour filter formed is arranged between two panels polarization plates, and one of polarization plates in front side are revolved
Turn simultaneously illuminated using fluorescent lamp (at 380nm to 780nm wavelength) from rear side, so as to use CS-2000 luminance meters (by
KONICA MINOLTA companies manufacture) measure the maximum intensity and minimum strength for launching light.Then, by maximum intensity divided by most
Value that small intensity is calculated defines contrast.
Aberration be by measure respectively at 200 DEG C colourity before and after in heating furnace continuous heating 25 minutes,
Then the value for the colourity (y) after heating being subtracted into the colourity (y) before heating and being calculated, it is in following ' the △ y ' of mathematical expression 1
Represent.
[mathematical expression 1]
△ y=y (after heating)-y (before heating)
Measurement result is shown in table 1.
(2) measurement of light transmittance
(manufactured using colour difference meter by Olympus companies, OSP-200), measure the light transmittance in visible region.
Measurement result is as shown in table 1.
[table 1]
Referring to upper table 1, it can be seen that in embodiment 1 and embodiment 2 prepared composition there is excellent viscosity and
Being layered of pattern, high developing powder, less aberration, excellent light transmittance and high contrast do not occur.
Find that there are the excellent all spies for including viscosity, developing powder, aberration, contrast and light transmittance by contrast
The colour filter of sign can not be used according to composition (at least one aforementioned properties are poor) prepared in comparative example 1 to 11 to make
Make.
