Composition for forming conductive pattern by irradiation of electromagnetic waves, method for forming conductive pattern using same, and resin structure having conductive pattern

A composition for forming a conductive pattern by irradiation of electromagnetic waves comprising:

• a polymer resin including a polycarbonate resin;
• and an electromagnetic wave-absorbing inorganic additive which absorbs an electromagnetic wave in the infrared region, and satisfies the characteristic that a laser sensitivity LS defined by Equation 1 below is 1.6<−log(Ls)<6.0:
• Laser sensitivity Ls=Re−1.4×wt×Iaa [Equation 1]
• In Equation 1 above,
• Re represents an effective radius of the electromagnetic wave-absorbing inorganic additive obtained by the equation of Re=300/[A(m2/g)×B(g/cm3)], from the BET specific surface area A(m2/g) and density B(g/cm3) of the electromagnetic wave-absorbing inorganic additive,
• wt is a value representing the content (weight) of the electromagnetic wave-absorbing inorganic additive in terms of a weight fraction relative to the total composition when the total content (weight) of the composition for forming a conductive pattern is 1, and
• Iaa represents an effective light absorption rate of the electromagnetic wave-absorbing inorganic additive obtained by the equation of Iaa=(1−IR)2/(2IR) (%), IR represents an absorbance (%) for electromagnetic waves having a wavelength in a predetermined infrared region having a wavelength of about 1,000 nm to 1,200 nm measured using a UV-vis-IR spectrum, relative to the electromagnetic wave-absorbing inorganic additive.
