Technical field
The present invention relates to the new mercaptan compound with bis-phenol skeleton, its preparation method, and relate to alkali developable type photosensitive composition that uses this compound and the black matix resist composition that is used for colour filter.More particularly, the present invention relates to the new mercaptan compound with bis-phenol skeleton, relate to the photosensitive composition that uses this compound and be used for the black matix resist composition of colour filter, said composition contains: the Photoepolymerizationinitiater initiater system that (A) comprises this compound; (B) has the adhesive resin of carboxyl; (C) have the compound of ethylenically unsaturated group, and said composition has hypersensitivity when alkaline development and the characteristic of excellent maintenance live width in thread pattern.
Background technology
Photosensitive composition is used for various fields, comprises press plate, color proofing, colour filter, solder resist and light-curable ink.Especially in recent years, the character of the tool feature of Photocurable composition such as the concern that room temperature operability, rapidly-curable and solvent-free property have been subjected to each field, comprise those from the environment aspect, the application considered such as energy-conservation, work safety, production cost, and photosensitive composition has been carried out many research and development.
Compound and various additive that photosensitive composition mainly solidifies, has ethylenic unsaturated bond by Photoepolymerizationinitiater initiater, adhesive resin, by polyreaction are formed, and the kind of these components depends on the purposes of photosensitive composition.
Photoepolymerizationinitiater initiater is selected according to photosensitive wavelength and polymerization initiation performance.Adhesive resin, the compound with ethylenic unsaturated bond and additive are selected according to the physicals of polymerizability and the cured product wanted.These components combine and are used to constitute photosensitive composition.
Yet, use some adhesive resin, some has under the situation of the compound of ethylenic unsaturated bond and some additive separately,
(1) can not obtain to cause photopolymerisable enough energy;
(2) can not obtain stability in storage;
(3) owing to the thickness of the solidifying product of wanting, it is enough dark that radiant light can not reach therein, causes curing insufficient;
(4) the part generation oxygen inhibition that contacts with air at photosensitive composition; With
(5) under alkaline development, the performance that keeps the thread pattern live width is low.
For those problems, various measures have been taked; For example, adopt bigger light ray radiation, excessive Photoepolymerizationinitiater initiater and the placement oxygen screened film of use.Yet, for energy-conservation and minimizing production cost, the photosensitive composition that need have higher sensitivity of light.
Wherein, in the colour filter performance history that is used for color TV, liquid-crystal display, solid state image sensing device, photographic camera etc., the colo(u)rant dispersion resist of considering to be used for colour filter is to boost productivity and higher sharpness. uses at this type of, to increasing day by day in the demand that more low-yieldly more promptly solidify down, can reach higher sharpness when forming pattern and have a photosensitive composition of more excellent curing depth.
The common following manufacturing of colour filter: on transparent substrate such as glass or plastics sheet surface, form the matrix (black matix) that trellis black, form three kinds or the multiple different form and aspect patterns such as red, green, blue of the tolerance range that reaches several microns then.Wherein, the configuration black matix is to improve contrast gradient and to prevent the TFT fault.Yet the resist (black matix resist) that forms this black matix has high photoresistance effect, therefore is difficult to photocuring in essence.But,, the demand of hypersensitivity is increased day by day along with the glass baseplate size increases.Simultaneously, even still can keep the almost constant resist of fine pattern live width, i.e. its excellence aspect the development latitude when needing strongly to be exposed to alkaline-based developer for a long time.
Recently, because liquid-crystal display begins to be applied to televisor,, and wish that pigment has higher concentration to the increase in demand of colour filter with excellent colour contrast.Yet, because highly enriched pigment can cause susceptibility to reduce.Therefore, for improving the susceptibility of photosensitive composition or black matix resist composition, advised using multi-functional thiol's compound (JP 10-253815A, JP 10-253816A, JP10-253817A, JP 2004-149755A etc.).
Yet, multi-functional thiol's compound of before having advised, because the polyol component of its basic framework of conduct that wherein contains is aliphatic, the problem that exists in by the photocuring product that uses this compound to obtain is: because the alkaline-resisting development of difference, the line widths shrink of thread pattern, the susceptibility of composition promptly has the insufficient problem of development latitude, although can improve.Especially, for the top black matix resist that will form the trellis pattern, it is very crucial that the phenomenon of thread pattern line widths shrink becomes.
Summary of the invention
The purpose of this invention is to provide when alkaline development that live width keeps constant excellent performance, the hypersensitivity photosensitive composition of the latitude of promptly developing excellence and black matix resist composition in thread pattern.
As the result of wholwe-hearted research, the present inventor has finished the present invention by following discovery: the problems referred to above can solve by photosensitive composition or the black matix resist composition that uses the new mercaptan compound with bis-phenol skeleton.

Using light microscope (VH-Z250, Keyence Corp. makes) to read is 4,6,8,10 at the optical mask pattern center line wherein, and 20,50 and 100 microns and all are spaced apart the minimum feature on 50 microns the part. The results are shown among the table 2-6.
[OD value (optical density (OD))]
Each anti-corrosion agent composition of embodiment 4-9 and Comparative Examples 3-5 is spun on the glass baseplate (100 * 100mm size), under the room temperature dry five minutes then, subsequently under 90 ℃ with solvent seasoning three minutes. With this product with 50mj/cm2Expose by ultrahigh pressure mercury lamp, to cure 60 minutes after then under 230 ℃. the glass baseplate measurement OD value .OD value that has applied the resist gained above the use is determined by calibration curve, this calibration curve makes by the transmission coefficient at 550nm place on the standard base material of measuring known OD value. then, the transmission coefficient that whenever carries out 550nm place once the glass baseplate that resist applies of embodiment and Comparative Examples is measured to calculate the OD value. and the results are shown in and show among the 4-6.
