Abstract
Provided are a surface protection composition which has excellent anticorrosion performance to prevent the metal corrosion, and also has excellent coating properties and heat resistance with suppressing cracks from being occurred even in a cold environment and maintaining anticorrosion performance, and a terminal-fitted electric wire using these.The present protection composition contains: (a) a phosphorus compound represented by the following general formula (1) in an amount of 0.1 to 10 mass % in terms of phosphorus element with respect to the total amount of the composition; (b) a metal-containing compound in an amount of 0.1 to 10 mass % in terms of the metal element with respect to the total amount of the composition or an amine compound in an amount of 0.1 to 5.0 mass % in terms of nitrogen element with respect to the total amount of the composition; (c) a (meth) acrylate having two or more carbon-carbon double bonds and hydrocarbon chains having four or more carbon atoms in an amount of 1.0 to 70 mass % with respect to the total amount of the composition; (d) a mono (meth) acrylate having a hydrocarbon chain having seven or more carbon atoms in an amount of 1.0 to 80 mass % …
