Provided is an insulating coating composition. The composition is highly safe, in which an organic material to form an insulating film is dissolved highly stably. The composition can form an insulating film by coating, where the insulating film has a low relative permittivity, a high insulation resistance, and high wettability and allows an upper layer to be formed thereon by coating. The insulating coating composition according to the present invention contains a cyclic olefin copolymer and a solvent. The cyclic olefin copolymer is a copolymer between a cyclic olefin and a chain olefin. The solvent includes a compound represented by Formula (1) and having a normal boiling point of 100° C. to lower than 300° C. In Formula (1), Ring Z is a ring selected from a 5- or 6-membered saturated or unsaturated cyclic hydrocarbon and a benzene ring; and R.sup.1 is selected from a hydrocarbon group and acyl. Ring Z has a substituent or substituents including the R.sup.1O group. When Ring Z has two or more substituents, two of the substituents may be linked to each other to form a ring with a carbon atom or atoms constituting Ring Z.

Embodiments in accordance with the present invention encompass compositions containing one or more polycycloolefinic monomers and at least one multifunctional olefinic monomer which when subjected to a suitable temperature undergoes mass polymerization to provide a three-dimensional insulating article which exhibits hitherto unattainable low dielectric constant and low-loss properties, and very high thermal properties. The compositions of this invention may additionally contain one or more organic or inorganic filler materials, which provide improved thermo-mechanical properties in addition to very low dielectric properties. The compositions are stable at room temperature and undergo mass polymerization only when subjected to suitable higher temperatures generally above 100° C. The compositions of this invention are useful in various applications, including as insulating materials in millimeter wave radar antennas, among others.
