Description
Technical Field
The invention relates to the technical field of photocuring materials, and particularly relates to a photoinitiation composition, a photocuring composition, a photoresist, application of the photocuring composition and application of the photoresist.
Background
Photocuring technology has been widely used since the 70 s, for example, UV photocuring technology is commonly used in the fields of coatings, printing inks, and electronic device manufacturing, wherein one of the most important concerns of the skilled person is curing efficiency or sensitivity, and the key factor influencing curing efficiency is photoinitiator structure and co-initiator components used in cooperation with the photoinitiator structure.
For example, the thioether oxime ester compounds proposed in patent publication No. CN1241562B are the most successful photoinitiators in photoresist formulations, such as commercial productsOXE01 has relatively good sensitivity and low yellowing, is well known to those skilled in the art, is widely studied and used, and is particularly effective in clear photoresist and RGB color photoresist formulations. Later International publication No. WO2002/100903 discloses oxime ester compounds having more complex substituents on the parent structure of diphenyl sulfide, and also discloses carbazole-parent oxime ester compounds, commercially available products such as those from BASF corporationOXE 02, although having improved sensitivity, also has a stronger yellowing, making its use in clear and color photoresists very limited. The Chinese patent applications with application publication numbers CN101565472A and CN103833872A are based on the above-mentioned patent compounds, and do not fundamentally change the sensitivity and yellowing of the corresponding oxime ester compounds, such as PBG305 and the corresponding oxime ester compoundsBis-ketoxime ester compounds 1, 3 and 4 disclosed in the PBG304 and CN103833872A patent application specifications; the CN101528694A patent application discloses oxime ester compounds with nitro carbazole as the parent, and the CN103153952A patent application discloses oxime ester compounds with benzo carbazole as the parent, because of the introduction of chromophore nitro group or the large conjugated structure of benzo carbazole, the ultraviolet absorption spectrum of corresponding oxime ester compounds is significantly red-shifted, such as NCI-831 of the company Aidicco and BASFTwo commercial products of OXE 03 have more efficient absorption of the 365nm emission from the light source, showing higher sensitivity, but at the same time, the significantly red shifted uv absorption spectrum also imparts a yellowish color to the compound and significant yellowing in the photoresist, so they are more suitable for use in black photoresist formulations and difficult to use in clear and RGB color photoresists.
In order to improve the color saturation or hiding power, the pigment content in the photocuring formula is higher and higher, especially for the black photoresist with high pigment content, the light energy utilization rate in the curing process is reduced due to the absorption of the pigment, a photoinitiator or a photoinitiator composition with higher sensitivity needs to be developed, and the sensitization of the existing photoinitiator is also one of the methods for improving the sensitivity. Sensitizers are frequently used in photocurable compositions, especially photoresist formulations. Sensitizers described in the prior art, such as disclosed in the CN1241562A patent application, are benzophenone and its derivatives, such as 4- (4-methylphenylthio) benzophenone (trade name Omnirad BMS) or 4, 4' -bis (diethylamino) benzophenone, thioxanthone and its derivatives, such as 2-isopropylthioxanthone, anthraquinone and its derivatives, such as 2-ethylanthraquinone, coumarin derivatives, such as 5, 7-dimethoxy-3- (4-dodecylbenzoyl) coumarin (Esacure 3644 from IGM resins), camphorquinone, phenothiazine and its derivatives, 3- (aroylmethylene) thiazoline, rhodanine and its derivatives, rhodamine, acridine, anthocyanidins, merocyanine dyes, eosin; among them, benzophenone and its derivatives, thioxanthone and its derivatives, anthraquinone and its derivatives, and coumarin derivatives are preferable. Experiments prove that the sensitizing agents do not show satisfactory sensitizing effects when used in combination with thioether oxime esters, and some compounds reduce the photocuring efficiency of the formula of the photocuring composition due to containing phenolic hydroxyl groups or anilino groups such as eosin, anthocyanin and phenothiazine; among the four preferred classes of compounds, although they are themselves photoinitiators, the photoinitiation efficiency is much lower than with the thiolyximide compounds, they do not exhibit synergistic sensitization when used in combination with thiolyximides, and some species such as 2-isopropyl thioxanthone and 2-ethylanthraquinone, for their own longer wavelength UV absorption spectrum, give severe yellowing to the formulation and are rendered unusable. There is no ideal sensitizer in the prior art.
However, the pursuit of the technicians for improving the properties such as exposure sensitivity, resolution, thermal stability and the like is never limited, and the existing products and formulation technologies face new challenges.
In order to improve the light transmittance of transparent photoresists and the color purity of color photoresists, the photoinitiator used needs to have lower yellowing, and thus there is still a need to develop new photoinitiator products with higher sensitivity and lower yellowing.
