- the transmittance was measured using an apparatus name: UV-2500PC (manufactured by Shimadzu Corporation).
- Table 1 shows the transmittance at a wavelength of 450 nm. Also, a graph of transmittance in the visible light region (wavelength 375 nm to 775 nm) of the pattern obtained in tests 1 to 3, that is, the pattern after secondary heat treatment at 200 ° C, 230 ° C, and 250 ° C. Are shown in Figs.
- a photosensitive resin composition is applied to a glass substrate by spin coating, and dried on a hot plate at 110 ° C for 90 seconds to form a photosensitive resin composition layer having a thickness of 1 ⁇ m. did.
- One Ide through a mask, to pattern exposure at an energy of 100 mj / cm 2, 2. to form a pattern development processing to using TMAH aqueous solution of 38 mass 0/0 concentration.
- the minimum space width that can be resolved was evaluated as “resolution”. This result Table 3 shows.
- a positive photosensitive resin composition was produced and evaluated in the same manner as in Example 1 except that the homopolymer (Mw: 6000) comprising the structural unit “PEMA” was used as the component (A).
- the results are shown in Table 1, Table 2, Table 3, and Figs.
- a positive photosensitive resin composition was produced and evaluated in the same manner as in Example 1 except that a homopolymer (Mw: 4000) having a structural unit force represented by the following chemical formula was used as component (A). These are shown in Table 1, Table 2, Table 3, and Figs.
- a positive photosensitive resin composition was produced and evaluated in the same manner as in Example 1 except that hydroxystyrene homopolymer (Mw: 10000) was used as component (A). The results are shown in Table 1, Table 2, Table 3, and Figs.
- CF Blue UM product name; manufactured by Mikuni Dye Co., Ltd.
- a natural rosin composition was produced. Then, using this pigment-containing photosensitive resin composition, a 2 m ⁇ 2 m dot pattern was formed in the same manner as in Example 1.
- the pattern could be obtained without any problem. Further, the obtained pattern was heated in the same manner as in the tests in Examples 1 to! -3. As a result, the pattern may collapse. There was no discoloration of the pattern.
- a positive photosensitive resin composition having good heat resistance and transparency can be provided. Therefore, the photosensitive resin composition of the present invention is useful for a light shielding layer such as a black matrix.
- the photosensitive resin composition of the present invention is useful for a colored layer of a color filter. In the present invention, a color filter having good heat resistance and transparency can be obtained.
