TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The composition (C1) comprises the polymer additive (at least 1 to 50 wt.%). Preferred Components: The naphthalene diimide has a lowest unoccupied molecular orbital energy level of 3.5-4.6 eV with reference to the vacuum energy level. The naphthalene diimide is selected from 6 compounds as given in the specification, e.g. compounds of formulae (I) and (II).A1 and A2=4-10C alicyclic ring;Y1=electron donating or electron withdrawing groups;m=0-4;R1-R10=H or electron donating organic;Y2=alkyl, alkenyl, alkoxy, aryl, arylalkyl, halo, cyano, fluoro-containing groups such as CF3, carbonyl-containing or carboxy-containing groups.In the compound (II), any two adjacent R groups on a ring system are combined to form four- to seven-membered alicyclic ring (optionally substituted).    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The polymer additive has a permittivity of 2-4 at 1000 Hz. The polymer additive is a styrenic polymer, polyalkylene, poly(meth)acrylate, polyalkene, polynaphthalene, and/or polycycloalkyl. The polymer additive comprises at least one of the following polymers having the low frequency (1000 Hz) permittivity: polystyrene (2.5), poly( alpha -methylstyrene) (2.6), poly( alpha -vinyl naphthalene) (2.6), poly(vinyl toluene) (2.6), polyethylene (2.2-2.3), cis-polybutadiene (2), polypropylene (2.2), polyisoprene (2.3), poly(4-methyl-1-pentene) (2.1), poly(4-methylstyrene) (2.7), poly(chlorotrifluoroethylene) (2.3-2.8), poly(2-methyl-1,3-butadiene) (2.4), poly(para-xylylene) (2.6), poly( alpha - alpha - alpha '- alpha ' tetrafluoro-para-xylylene) (2.4), poly(1,1-(2-methyl propane)bis(4-phenyl)carbonate) (2.3), poly(cyclohexyl methacrylate) (2.5), poly(chlorostyrene) (2.6), poly(2,6-dimethyl-1,4-phenylene ether) (2.6), polyisobutylene (2.2), poly(vinyl cyclohexane) (2.2), poly(vinyl cinnamate) (2.9), poly(4-vinyl biphenyl) (2.7), and poly(methyl methacrylate) (3.1-3.5).
