| titleOfInvention | Developing method for printed circuit board |
| abstract | The present invention relates to a developing method using a photosensitive liquid composition for an ultra-precision pattern printed circuit board, more specifically, 30 to 40% by weight of an acrylic copolymer resin represented by the following formula (1), pentaerythritol triacrylate, trimethylol propane 5-20% by weight of one or more photocrosslinkers selected from the group consisting of triacrylate and dipentaerythritol monohydroxy acrylate, 1-10% by weight photoinitiator, 0.1-1% by weight optical image former, and the rest The present invention relates to a method for developing a printed circuit board with a simple and high resolution by using a photosensitive liquid composition composed of a solvent and other additives.n n n Formula 1n n n n n n n n In the above formula, n, m, x and y are the moles of each component, and when n + m + x + y is 1, n is 0.5 to 0.8, preferably 0.6 to 0.65, m is 0.1 to 0.4, and x + y is 0.1 or less and x: The mixing ratio of y is 2-3. |
