    Abstract: A polyimide component being transparent includes a dianhydride monomer and a diamine monomer. The dianhydride monomer has an asymmetric structure. The dianhydride monomer has at least one first polar group and at least one side chain group. The first polar group is an ester group. A molecular structural formula of the side chain group is: The diamine monomer has an asymmetric structure and at least one second polar group. The second polar group is at least one of a nitrogen heterocycle and an ether group. The polyimide component is polymerized by the dianhydride monomer and the diamine monomer. The disclosure also relates to a polyimide film and a polyimide copper clad laminate.

    Abstract: A non-toxic water soluble photosensitive resin composition able to function as a solder mask coating comprises a polymer containing oxazolinyl, a photosensitive monomer, and a photo-initiator. These elements are all water soluble or water dispersible. The polymer containing oxazolinyl and the photosensitive monomer have a plurality of carbon-carbon double bonds. The polymer containing oxazolinyl and the photosensitive monomer are polymerized to form a dense cross-linking network structure when the water soluble photosensitive resin composition is exposed to ultraviolet radiation. A film using the water soluble photosensitive resin composition is also provided.
