Example embodiments provide a resin layer, a light transmitting laminate, and a vehicle. The resin layer includes at least one laminating layer containing a polyvinyl acetal resin, a plasticizer, and a bonding strength modifier. The surface of the laminating layer includes a portion having a hydrophobicity of 3.5 to 10, as calculated by Equation 1:Hydrophobicity=Non-polarity/polarity (1)where the non-polarity represents the non-polar fraction of the surface free energy of the laminating layer and the polarity represents the polar fraction of the surface free energy of the laminating layer.The resin layer has good shelf moisture resistance, undergoes less change in yellowness index, and has effectively controllable bonding strength due to its controlled hydrophobicity.
