FIELD: dielectric constant simulating compositions used as insulating materials or circuit board capacitors.
SUBSTANCE: proposed composition has splitting compound A, non-splitting compound B in the form of compound resistant to acid produced by acid source material C of definite dielectric constant or compound resistant to base produced by base source material C of definite dielectric constant in the amount of 5 to 900 parts by weight relative to component A and component B 100 parts by weight taken together.
EFFECT: enhanced difference between initial and changed dielectric constants and stability of dielectric constant simulator and relevant optical material irrespective of operating conditions.
