[0002] Photosensitive wet film is a film material commonly used to make the photoresist layer of circuit boards. The production process of photosensitive wet film can basically be divided into the following steps:

[0003] 1. Cover the photosensitive wet film on the PCB to be manufactured, and expose and develop it under light conditions to produce the required photolithography pattern;

[0004] 2. Heat the photosensitive wet film to solidify it and bond it to the substrate surface;

[0005] 3. Perform etching or chemical processing to remove the uncured parts, leaving the required photolithography pattern to produce the photoresist layer of the circuit board.

[0006] The main characteristics of photosensitive wet film are short development time, high resolution, good viscosity, good process stability and surface flatness, and the ability to produce high-precision lithography patterns.

A light-variable layer is also arranged between the light-shading layer and the surface layer, and the light-variable layer is formed by luminescent powder, light-variable powder and resin coating. The utility model arranges a light-variable layer made of luminescent powder and light-variable powder to ensure that the photosensitive film can absorb light energy to emit light and change color regardless of whether the lighting conditions are strong or weak, so that the pattern or warning sign is more prominent, thereby attracting attention, and also increasing the cool effect of the pattern. It can be widely used in road traffic and daily necessities.

[0008] The existing photosensitive wet film has a relatively single function when in use, and various problems will occur after use, affecting the quality of the product. At the same time, the material of the existing photosensitive wet film does not have environmental protection function, has certain harm to human health, and does not conform to the concept of green development.
