- the 41-step tablet was exposed with an energy amount of 23 steps after development.
- the resolution was evaluated based on the smallest value of the space width between the line widths where the unexposed areas could be removed cleanly by the development process. The results are shown in Tables 6 and 7.
- the evaluation of resolution means that it is so favorable that a numerical value is small.
- the photosensitive resin composition layer of the photosensitive element was laminated on a copper-clad laminate.
- a photosensitive resin composition layer comprising a phototool having a 41-step tablet and a phototool having a wiring pattern with a line width Z space width of 6Z30 to 47Z200 (unit: ⁇ m) as an adhesive evaluation negative
- the 41-step tablet is exposed with an energy amount of 23 steps after development. I got it.
- the adhesion was evaluated by the minimum value of the line width that adhered without peeling after development. The results are shown in Tables 6 and 7.
- the evaluation of adhesion means that the smaller the minimum value of the line width, the better.
- the photosensitive resin composition layer of the above photosensitive element was dissolved in 1.0 mass% sodium carbonate aqueous solution at a ratio of 0.25 m 2 of photosensitive resin composition layer per liter of sodium carbonate aqueous solution.
- the solution was then published with 1 LZ of air at 30 ° C. for 3 hours.
- scum scum dispersibility generated in the solution was visually evaluated based on the criteria shown in Table 5.
- the sludge generated in the solution was separated and filtered by a centrifuge, dried at 150 ° C. for 4 hours, and the sludge mass was measured.
- a photosensitive resin composition excellent in tent reliability capable of forming a cured film having sufficient mechanical strength and flexibility and The photosensitive element used, the method for forming a resist pattern, and the method for producing a printed wiring board can be provided.
