Invention field
The present invention relates to new Hexaarylbiimidazole compound.More particularly, the present invention relates to and in being used as the photopolymerizable composition of resist, to produce the Hexaarylbiimidazole compound that agent is used as optical free radical, and it is characterized by the pyrolysis product of low distillation, relate to the photopolymerization initiator composition that contains optical free radical generation agent and relate to the photopolymerizable composition that utilizes them.Photopolymerizable composition of the present invention is suitable for use as resist or is used as the colored filter of color liquid crystal display device, photographic camera etc.
Background of invention
Photopolymerizable composition (photosensitive composition) is widely used for some fields, comprises resist field (photoresist, solder resist, anti-etching dose, or the like).
In recent years, particularly the requirement for the photopolymerizable composition that can be used as the use of colored filter resist improves, and said composition will satisfy stability, high resolving power and high heat resistance and the sunproof requirement that comprises highly sensitive, prolongation for outstanding characteristic at the colored filter that is used for colour liquid crystal display device, color video camera or the like.
Colored filter is normally by for example forming black matix on the surface of glass in transparent substrates, forms for example red, green and blue three kinds or more kinds of colored striped mutually or mosaic pattern then to reach several microns precision.
A kind of typical production method of colored filter is exactly to utilize the colo(u)rant dispersion method of coloured composition, and this coloured composition is by preparing colo(u)rant dispersion in photosensitive composition.Because the precision height of the colored filter location of pixels of colo(u)rant dispersion method and film thickness, wearing quality (comprising photostabilization and thermotolerance) is outstanding and production rate defective (for example aperture) is low, it is widely used.
The colo(u)rant dispersion method contains the photosensitive composition of pigment and utilizes photoetch method by applying in substrate, forms various color layers according to the appointed pattern pattern.Particularly, it is for example on glass that the photosensitive composition that will be used for a kind of color filter color is coated in transparent substrates, and make it carry out pattern exposure, by developing with solvent or alkaline aqueous solution unexposed part removed, and forms first kind of multi color pattern.Then all color filter colors are repeated this method, to finish the manufacturing of colored filter.Consider the character of colored filter and many materials, photosensitive composition is the negativity type normally, and for fear of environmental problem, with an organic solvent develops hardly, and promptly most of photographic developers are to use the alkaline-based developer of alkaline aqueous solution.
In these production stages, drying after development step is (the back oven dry) that is in daily use.That is to say that after development treatment, the transparent substrates that will have the curing photoactive layer (having another name called color layer, pixel layer or resist layer) of formed pattern was for example heating (oven dry) about 10-120 minute under about 160-250 ℃.The wearing quality of color layer with chemistry and physics given in the back oven dry.
Yet the conventional photosensitive composition that is used for resist usually produces distillation during the oven dry after developing.These sublimates stick on the vapor pipe etc., and in case adhere to, and will drop on the resist layer and give rise to trouble.This instructs people to want to develop even the photosensitive composition, particularly development that can anti-sublimate during baking step generate use the photosensitive composition of the Photoepolymerizationinitiater initiater of high sensitive, low distillation.
Is known (referring to following patent documentation 1) based on the compound of Hexaarylbiimidazole as the purposes of the component of the photopolymerization initiator composition that is used for photosensitive composition, for example, use 2,2 '-two (2-chloro-phenyl-s)-4,4 '-5,5 '-tetraphenyl-1,2 '-diimidazole (HABI) is as the photosensitive composition of colored filter, by following formula (4) expression, it is disclosed among open HEI No.6-75372 (referring to following patent documentation 2) of Japanese unexamined patent publication No. and the open No.2000-249822 (referring to following patent documentation 3) of Japanese unexamined patent publication No. as the component in the photopolymerization initiator composition.Yet the distillation problem during the oven dry of back does not relate in these documents, certainly, does not propose the substituent Hexaarylbiimidazole compound of the present invention that has that can address this problem yet.

Embodiment 2, and the comparative example 1,2
Except consumption in the table 1 is listed in use, with and embodiment 1 same method carry out embodiment 2 and comparative example 1 and 2.The physicals of the photopolymerizable composition that obtains is according to the method assessment of embodiment 1.The results are shown in Table 1.
Assessment method
(1) residual film photosensitivity
The photopolymerizable composition that obtains is spin-coated on substrate of glass, and (100 * 100mm) go up to about 1.5 microns build, and at room temperature dry 30 minutes, vacuum-drying at room temperature was 10 minutes then.With film thickness surveying instrument (SURFCOM130A, Tokyo Seimitsu Co., Ltd. product) accurately measure the film thickness of exsiccant coating, then with having ultrahigh pressure mercury lamp (Ushio, Inc. exposure apparatus " Multilight ML-251A/B ") is exposed in the light photopolymerizable composition, change exposure by quartzy photomask simultaneously, be used for phototype setting.Utilize ultraviolet integrating photometer (Ushio Inc. " UIT-150 " that have " UVD-S365 " receptor) to measure exposure.In employed quartzy photomask, formed 5,10,30,50,70,100 microns straight line/space diagrams.Gap between photomask and coating is set to 100 microns.The coating of will exposing is at 0.1% aqueous sodium carbonate neutral and alkali develop the specified time (25 ℃).Development time is set to 1.5 times of time cycle (tD), and tD dissolves the needed time by the alkaline development of coating with coating before the exposure fully.Time cycle tD dissolves the needed time fully by the coating that repeated experiments is measured, and wherein observes the solubleness of the coating with different alkaline development times.After the alkaline development,, measure the film thickness of remaining coating (resist), calculate the remaining ratio of film according to following equation by spraying into air with substrate of glass washing and dry:
The remaining ratio (%) of film=100x (film thickness after the alkaline development)/(film thickness before the alkaline development) carries out identical phototype setting method, change exposure simultaneously, on the chart relation between exposure and the remaining ratio of film is being mapped then, wherein the remaining ratio of recording film reaches the exposure (mJ/cm of fullness of shade
2), with it as the remaining light sensitivity of film.Less value shows to have higher light sensitivity.
(2) sublimate during the oven dry of back
The photopolymerizable composition that obtains is spin-coated on substrate of glass, and (100 * 100 * 1mm) go up to about 1.5 microns build, and at room temperature dry 30 minutes, vacuum-drying at room temperature was 10 minutes then.With above-mentioned exposure apparatus irradiation 100mJ/cm
2Light, carry out phototype setting.The substrate that obtains is placed in the dish, dish is placed on makes its heating on the hot-plate then.(200 * 200 * 1mm) are placed in the dish, and will wrap aqueous dish and be placed on it, to cool off the stainless steel-based end with the stainless steel-based end.Use hot-plate after heating 30 minutes under 230 ℃ substrate of glass, with opticmicroscope (VH-Z250, the product of Keyence Corporation) observes the sublimate that is derived from cured film and stick at stainless steel-based the end, and visually judge existence or do not have crystal.The results are shown in Figure 5 (embodiment 1) and Fig. 6 (comparative example 1).When using HABI,, there is not tangible crystal when using MHABI although produced crystal (in Fig. 6 and the similar mark of bird footprint).
