This invention provides a method for forming multilayer coating film, which comprises successively carrying out a step of applying an intermediate paint onto a coating object to form an intermediate coating film; a step of forming a base coating film by applying onto the intermediate coating film a water-based base coating paint; a step of forming a clear coating film by applying onto the base coating film a clear coating paint, and a step of heating the uncured intermediate coating film, base coating film and clear coating film to simultaneously cure these three coating films; wherein the intermediate paint has a complex viscosity at 40&#xb0; C. (&#x3b7;*) of not higher than 100 Pa&#xb7;sec under the conditions of shear stress, 1.0 Pa and frequency, 0.1 Hz, and a complex viscosity at 80&#xb0; C. (&#x3b7;*) of at least 800 Pa&#xb7;sec under the conditions of shear stress, 1.0 Pa and frequency, 0.1 Hz.

Method for forming multilayer coating film

The present invention discloses a photocurable composition for forming an anti-fogging coating, comprising: (A) a urethane compound containing at least two (meth)acryloyl groups and a polyoxyalkylene chain in a molecule thereof, (B) a compound having at least two (meth)acryloyl groups and at least two hydroxyl groups in a molecule thereof, obtained by reacting at least two components consisting of an epoxy compound and (meth)acrylic acid, (C) a compound having an ethylenic unsaturated group other than the components (A) and (B), and (D) a photopolymerization initiator, and also discloses a method for forming an anti-fogging coating using this composition.
