Abstract
Description
透明基材と、
前記透明基材上に備えられ、屈折率が1.450〜1.485であるコーティング層と、
前記コーティング層上に備えられた金属箔パターンとを含み、
前記金属箔パターンのコーティング層と接する面の十点平均粗さ(Rz)は0.9μm超過である発熱フィルムを提供する。
金属箔フィルム上に屈折率が1.450〜1.485であるコーティング層を形成するステップと、
前記コーティング層上に透明基材を形成するステップと、
前記金属箔フィルムをパターニングして金属箔パターンを形成するステップとを含み、
前記金属箔パターンのコーティング層と接する面の十点平均粗さ(Rz)は0.9μm超過である発熱フィルムの製造方法を提供する。
前記発熱フィルムと、
前記発熱フィルムのいずれか1つの面に備えられる第1ガラスと、
前記発熱フィルムの他の一面に備えられる第2ガラスとを含み、
前記発熱フィルムと第1ガラスとの間の面、および前記発熱フィルムと第2ガラスとの間の面のうちの少なくとも1つの面には第2合わせフィルムを含むものである自動車用発熱ガラスを提供する。
屈折率が1.47、ガラス転移温度(Tg)が32℃のPVB12重量部、エタノール44重量部、メチルエチルケトン44重量部の組成を有するコーティング液を、厚さ3μmおよび8μmの銅箔のmatt面にコーティングした後、120℃、10分間乾燥して、銅箔のmatt面上に厚さ5μm〜7μmのPVB層を形成した。この時、3μmの銅箔のmatt面のRzは1.5μmであり、8μmの銅箔はRzが1.63μmであった。一方、3μmの銅箔に対して、380nm〜780nmの波長で測定したmatt面の平均反射率は7.6%であった。
屈折率が1.47、ガラス転移温度(Tg)が32℃のPVB14重量部、エタノール43重量部、メチルエチルケトン43重量部の組成を有するコーティング液を、厚さ3μmの銅箔のmatt面にコーティングした後、120℃で3分間乾燥して厚さ5μm〜7μmのPVB層を形成した後、110℃のホットロールラミネータで50μmの厚さのPETと熱ラミネーションして基材を製造した。この時、使用した3μmの銅箔のmatt面の表面粗さは1.5μmであり、380nm〜780nmの波長で測定した平均反射率は6.7%であった。3μmの厚さの銅箔の場合、フィルム工程の取扱容易性のために、背面に18μmのキャリア箔が付着しているので、パターンの形成前にこれを除去した。印刷工程で厚さ100nm〜400nmのノボラック樹脂ベースのレジストパターンを形成した後、硫酸5%/過酸化水素5%ベースのエッチング液でエッチングして、レジスト除去工程なしに発熱フィルムを製造した。
matt面の表面粗さが1.5μmであり、この面に対して380nm〜780nmの波長で測定した平均反射率が6.7%である3μmの厚さの銅箔に対して、実施例2と同様の方法で、屈折率が1.47、ガラス転移温度(Tg)が32℃のPVB14重量部、エタノール43重量部、メチルエチルケトン43重量部の組成を有するコーティング液を、厚さ3μmの銅箔のmatt面にコーティングした後、120℃で3分間乾燥して厚さ5μm〜7μmのPVB層を形成した。この後、実施例2と同様の方法でPETラミネーションおよび背面18μmのキャリー箔の除去、レジストパターン形成および銅エッチング工程を経たフィルムに対して、3%NaOH水溶液でレジストを除去した後、セレンベースの黒化液に30秒間浸漬して、空気に露出した銅表面を黒化した。この時、PETフィルムとPVBシートおよびPVBコーティング層との密着力強化のために、PETは両面に2.5nmのNbOx層が蒸着されたPETフィルム(厚さ50μm)を用いた。
屈折率が1.44のシリコーン系高分子が主成分である粘着層がPETと銅箔との間に形成された基材を用いて、レジストパターニング、エッチングおよび剥離工程により発熱フィルムを製造した。この時、キャリア箔を除去した後の銅箔の厚さは2μmであった。エッチングまでのみ進行させた場合と、レジスト剥離まで進行させた場合のフィルムに対して、それぞれフィルム状態での光特性と、ガラス貼り合わせ後の光特性は下記の図5に示した。
屈折率が1.47、ガラス転移温度(Tg)が32℃のPVB20重量部、N−メチルピロリドン80重量部の組成を有するコーティング液を、表面粗さRz2.0μmである厚さ2μmの銅箔のmatt面にコーティングした後、常温でovernight放置後、80℃で10分、110℃で3分間乾燥するか、その他の温度プロファイルで乾燥して、銅箔に厚さ50μmのPVB層を形成した。この時、常温でovernight放置後、80℃で10分、110℃で3分間乾燥時には、銅箔/PVB基材のカール(curl)が非常に激しくてPETとのラミネーションが難しかった。乾燥速度を速くする場合には、基材の内部に残存する溶媒によってPETとのラミネーション後にバブルが観察された。
屈折率が1.47、ガラス転移温度(Tg)が32℃のPVBシート12重量部、エタノール44重量部、メチルエチルケトン44重量部の組成を有するコーティング液を、厚さ6μmの銅箔にコーティングした後、120℃で4分間乾燥して、厚さ5μm〜7μmのPVB層を形成した。この時、使用した6μmの銅箔のRzは0.7μm、380nm〜780nmの波長で測定したmatt面の平均反射率は68%であった。この場合、120℃、1.7mpmの速度で銅箔のPVB面に50μmの厚さのPETを熱ラミネーションした後にも銅箔/PVB層とPET層との密着力が確保されず工程が不可で、最終的に基材を製造するためには、110℃で3日間追加的なagingが必要であった。
屈折率が1.612のエポキシ系高分子が主成分である接着層をPETと銅箔との間に形成させ、60℃で1日間熟成した基材を用意した。レジストパターニング、エッチングおよび剥離工程により発熱フィルムを製造した。この時、キャリア箔を除去した後の銅箔厚さは2μmであった。この後、前記発熱フィルムの両面に0.38mmの厚さのPVBシートと、最外郭層にガラスとを積層して、ガラス/PVBシート/発熱フィルム/PVBシート/ガラス構造を設けた後、120℃の温度で20分間真空ラミネーション後、140℃の温度で20分間真空ラミネーションして発熱合わせガラスを製造した。このように製造した発熱合わせガラスのヘイズは3.5%であった。
屈折率が1.492のウレタン系高分子が主成分である接着層がPETと銅箔との間に形成された基材を用意し、レジストパターニング、エッチングおよび剥離工程により発熱フィルムを製造しようとした。銅箔の厚さは8μmであった。この時、リン酸/硝酸/酢酸の混合液からなるエッチング液を用いてエッチングをする場合、ウレタン系高分子層が損傷してパターニングを進行させることができなかった。硫酸と過酸化水素が主成分であるエッチング液を用いた場合にも、安定的なパターニングを進行させにくかったが、一部の良好な領域に対して、両面に0.38mmの厚さのPVBシートと、最外郭層にガラスとを積層して、ガラス/PVBシート/発熱フィルム/PVBシート/ガラス構造を設けた後、140℃の温度で30分間真空ラミネーションして発熱合わせガラスを製造した。このように製造した発熱合わせガラスのヘイズは2.6%であった。
