Disclosed is an epoxy resin composition which is solid at ordinary room temperature, cures with excellent light resistance and heat resistance and minimal shrinkage, and is useful for encapsulating LEDs. The epoxy resin composition is characterized by comprising as an essential component an epoxy resin having an epoxy equivalent of 300-1000 g/eq and a softening point of 65-110&#xb0; C. obtained by reacting a nonaromatic polycarboxylic acid (A) having an acid value of 100-250 mgKOH/g with a nonaromatic epoxy resin (B) having an epoxy equivalent of 100-400 g/eq. The nonaromatic polycarboxylic acid (A) may be obtained by reacting 1,4-cyclohexanedimethanol, 2,2-bis(4-hydroxycyclohexyl)propane, or 3,9-bis(1,1-dimethyl-2-hydroxyethyl)-2,4,8,10-tetraoxaspiro[5,5]undecane with methylhexahydrophthalic acid or hexahydrophthalic acid.

A printing press comprises a pair of left- and right-frames, a first printing plate guiding device provided at a location near a lower plate cylinder, swingably supported so as to be moved between a guiding position for guiding a new printing plate supplied to a lower plate cylinder or a discharged printing plate discharged from the lower plate cylinder and a shelter position released from the lower plate cylinder, a second printing plate guiding device provided at a location near the lower plate cylinder, swingably supported so as to be moved between a guiding position for guiding the new printing plate or the discharged printing plate and a shelter position released from the lower plate cylinder and a safety cover swingably supported so as to be moved between a closing position for closing at least one part of a space formed between the left- and right-frames and a releasing position for releasing the space. The first printing plate guiding device, the second printing plate guiding device and the safety cover are coaxially supported on a supporting axis. Thus, an operation space can be provided at a location near a plate cylinder even if a sufficient space is not provided above a printing unit.

The solar heat-shielding paint composition of the present invention contains a solar heat-shielding pigment having a grain size of 50 .mu.m or less in a proportion of from 2 to 60% by weight of the solid content of the composition as a part or all of the pigment. The solar heat-shielding paint-coated structure having an outermost overcoat layer made of the said paint composition on the structure base displays an excellent solar heat-shielding effect and has a long-time durability with no problem of environmental pollution. The overcoat may be colored in any desired color to give a beautiful outward appearance. The coated structure is extremely useful as an outdoor structure, for example, marine structures such as decks or tanks of ships, as well as land structures such as architectures of petroleum tanks, houses, buildings, storehouses or gymnasia, and cars, tank lorries and refrigerator containers.
