  • Publication number: 20220162359
    Abstract: The present application may provide a curable composition comprising a polymer component including an alkyl acrylate unit having a straight or branched alkyl group, a hydroxy group-containing monomer unit and a nitrogen-containing monomer unit, and a curing agent, and the curable composition has excellent step absorptivity, and step embedding and punching properties, and can prevent white turbidity, and is capable of implementing a low dielectric constant and improving the punching performance and handling properties. Even if such a curable composition according to the present application is applied to a stepped substrate or the like, it may prevent lifting or delayed bubbles from being generated in the step portion. In addition, the pressure-sensitive adhesive film comprising the cured product formed from the curable composition may have excellent tensile strength.
